93; Not long to go now. Palace have one last go and it nearly results in a goal as Murray collects at the far post, turns Cresswell and sees Adrian save his goalbound shot. Palace win a corner, but the Hammers deal with it comfortably enough.
90: A final change for the Hammers, with Mohamed Diame coming on for Stewart Downing. Meanwhile, the fourth official has signalled four minutes of added time.
87: Time ticking down now and Cole's goal came at the perfect time for the Hammers, taking the heat out of the contest as Palace looked for a route back. There's still some defending to do though and Vaz Te buys some time by drawing a foul from Delaney.
83: Mauro Zarate goes off to a standing ovation from the away support, and Diego Poyet is on for his Barclays Premier League debut. Meanwhile, Glenn Murray comes on for Stuart O'Keefe for the hosts.
81: A glimmer of an opportunity for Bolasie as the hosts work the ball wide into the right channel, but Reid comes across well to get a well-timed block in.
76: Sakho close to a debut goal there as Kouyate goes bounding off down the right again, he feeds Downing, whose cross is met by Sakho, forcing a flying save from Speroni.
70: Crystal Palace make a brace of changes, with Jonny Williams and Dwight Gayle replacing Barry Bannan and Frazier Campbell. The home fans don't seem too impressed with Bannan's withdrawal.
69: Sakho gets himself involved straight away, winning a corner off Ward with an ambitious shot. Noble's near post corner is headed clear though.
67: Carlton Cole's race is run. It's been a productive one though with his strike restoring the Hammers' two-goal advantage. Debutant Diafra Sakho is on in his stead.
62: GOAL! That should settle a few nerves. Palace concede a free-kick on halfway, when Noble wins possession back and gets fouled. Tomkins lofts into the box and as Vaz Te challenges Delaney can't get any purchase on his clearance. Cole is waiting to bounce and fires into the bottom left corner. 3-1 West Ham.
59: West Ham are in trouble when Zarate goes down in his own half expecting a foul. Nothing doing for referee Clattenburg and Campbell can run at the Hammers backline. He drags inside Tomkins but loses his footing as O'Brien closes down and West Ham can scramble clear.
55: West Ham really need to slow the game down a bit and try to draw some of Palace's sting. Bannan is given too much time to line-up a shot from 25 yards out, but Adrian is able to gather at the second attempt.
52: Zarate is blocked off by Bolasie and drags him down to concede a free-kick out wide. It comes to nothing, but the complexion of the game has changed with the Selhurst Park crowd right up for this now.
49: Goal! It's a let off the Eagles take full advantage of as on their next attack, they shift the ball inside to Chamakh in space 25 yards out. He takes a touch and drills into the bottom left corner. No chance for Adrian and all of a sudden it's game on.
47: That really should have been game over. Downing delivers a corner from the right and Tomkins climbs almost unchallenged at the far post, but heads against the bar with Speroni helpless. A real let off for the home side.
46: We're back underway at a sunny Selthurst Park. No changes for either side.
HT: An impressive 45 minutes from the Hammers, who were in total control of that. Big Sam will be delighted that, unlike last week, they've made it count with two goals of the highest quality from Zarate and Downing. 2-0 and more of the same in the second half please.
45+4: Kouyate is down, receiving treatment to his arm, but he shrugs it off to continie.
45+2: Palace try a clever free kick from their routine as Jedinak passes low into the box. Bolasie's eventual shot is blocked, and Delaney slams the rebound into the side netting from an impossibly tight angle.
45+1: We'll have three minutes of added time and in the first of those, Tomkins joins fellow centre half Reid in the book, as he takes down Bolasie as he looks to get past him 25 yards out.
42: West Ham aren't taking their foot off the pedal here. Vaz Te shoots from range and Speroni can't gather first time, but he recovers to claw the ball in as Cole bears down.
40: Yellow card for Reid. The Hammers think they should have had free-kick themselves when Cole went down. The linesman was flagging furiously, but Clattenburg overrules him and Palace play on. Reid cuts Chamakh down and he goes into the book.
37: GOAL! What a couple of minutes for the Hammers! Downing picks up possession on the right hand touchline, shifts inside with his first touch and opens up the space on Ward to shoot. It's an invitation which he has no hesitation in taking, stroking into the bottom left hand corner and leaving Speroni with no chance from 20 yards. 2-0!
35: West Ham have a chance for a quickfire second as O'Brien advances into the box but fires wide of the near post as he gets his shot away.
34: GOAL! The Hammers make their pressure count with a finish of real quality. They win a corner down the left, which Downing and Vaz Te work short to Noble. His shot is blocked by Campbell, but the ball loops up towards Zarate 20 yards out, who catches it flush on the volley to beat Speroni into the bottom right corner. Fine finish!
30: Zarate is looking to get involved at every opportunity, dropping into midfield positions to pick up possession. He collects 35 yards out and advances ten more before sending in a shot. He doesn't quite get hold of it though and it's an easy save for Speroni.
28: West Ham getting more and more on the front foot now as Vaz Te finds a pocket of space on the left and waits until Zarate advances into the box. He rolls into feet but the Argentine can't bring it under his spell and the ball runs away from him and out for a goal kick.
26: The Hammers are getting Downing in the game more now and a neat bit of trickery shrugs off Bannan's attentions and allows him to cross right footed. It goes beyond the attacking Hammers but O'Keefe has to turn around, with a touch which had Speroni worried for a second. It's only a corner though.
24: Big chance for the Hammers as Downing's floated cross to the back stick cuts Speroni out and finds Cole, who nods back into the danger zone, where an onrushing Cresswell produces a shot which takes a nick off a defender and rolls behind.
20: Noble takes a quick free-kick short to O'Brien, who crosses towards the penalty spot. Cole gets his head to it, but there's too much pressure on the ball and Speroni gathers his bouncing effort comfortably.
16: Aaron Cresswell has his first real chance to advance down the left, and he shows a good turn of pace to get close to the by-line, but Kelly sticks with him and blocks the cross behind for a corner. Speroni catches the delivery and Palace can take a breather.
14: There's a scare for the Hammes as Bolasie is able to deliver a cross from the left which Chamakh cleverly chests back to Jedinak, who is in space 20 yards out, but Noble is positioned well to block.
10: Kouyate bounds down the right to get himself in a crossing position. His delivery is nodded to Cole by Vaz Te. He controls on his chest and lays off to Zarate outside the box, who is closed down well and his shot his blocked. Good approach work from West Ham though.
9: Kouyate, who impressed with an all-action performance on debut last week, gets his foot in to start a Hammers attack inside his own half. He's fouled before he can make any headway though and Palace regroup.
5: Palace find a route into Hammers territory for the first time with right back Kelly getting the better of Vaz Te and crossing dangerously to the far post, where Reid gets in front of Chamakh to head behind. Palace have a corner but it comes to nothing as the Hammers survive that moment.
3: Zarate is making his first start in Hammers colours today and he makes an early impression, collecting possession on halfway and spinning away from his man before driving deep into Palace territory and drawing a foul.
2: Hammers with the early possession here at Selhurst Park. Vaz Te is clipped by Kelly and it's a free kick for West Ham down the left. Noble hoists it into the box from deep, but Palace work it clear.
0: We're underway. Come on you Irons!
2.58pm: Almost 3,000 Hammers fans are over in the Arthur Wait Stand on the far side. They're making a good effort matching up against the lively Palace support!
2.56pm: The teams make their way out of the tunnel, West Ham all in sky blue and led by skipper for the day Mark Noble.
2.50pm: Manager Sam Allardyce has confirmed in his pre-match interview that Kevin Nolan could be sidelined for a few weeks with his shoulder injury. The skipper was hurt in training on Thursday. In his absence, Mark Noble will captain the Hammers this afternoon.
2.50pm: The sun is still bathing Selhurst Park as the two teams head back inside for their final preparations. So, can the Hammers score their first win in this part of south east London in 23 years? Let us know on Twitter using the hashtag #CPLWHU.
2.35pm: Aston Villa have gone top of the table following their goalless home draw with Newcastle United in the lunchtime kick-off. That result also took Newcastle above the Hammers, who slip to 19th. All very early days, of course!
2.30pm: So, what do you make of the Hammers' new-look starting XI? Mauro Zarate has a big chance to shine on his full debut, playing with Carlton Cole in attack. At the back, the timely return of James Tomkins from a groin injury means James Collins should not be too sorely missed.
2pm: The team news is in! West Ham make two enforced changes, with the suspended Collins and shoulder injury victim Nolan replaced by Tomkins and Zarate respectively. The Argentine is handed his full debut at Selhurst Park, where he will be aiming to beat fellow countryman Julian Speroni to score his maiden Hammers goal. Palace replace the suspended Puncheon with Bannan.

Good afternoon and welcome to south east London and Selhurst Park, the home of Crystal Palace.
West Ham United, who were edged out 1-0 at home by Tottenham Hotspur last weekend, contest their first away fixture of the 2014/15 Barclays Premier League season against an Eagles side also seeking their first points of the campaign.
Palace, who find themselves with Keith Millen in caretaker charge following the departure of Tony Pulis, also fell victim to an injury time goal themselves. Arsenal were their conquerors at the Emirates, with Aaron Ramsey notching at the death after Laurent Koscielny cancelled out summer signing Brede Hangeland's first half opener.
Both sides are going to have to make enforced changes this afternoon after having a player sent-off a week ago. James Collins, who turns 31 today, was red carded for the Hammers, while Jason Puncheon was sent-off for the Eagles - both for two bookable offences.
Meanwhile, Collins' fellow defender James Tomkins remains doubtful with a hamstring problem, while Matt Jarvis could also miss out, along with Carl Jenkinson (both hamstring).
For Crystal Palace, defender Scott Dann has an outside chance of being involved as he battles to beat a hip strain. Defender Adrian Mariappa (ribs), midfielder Jonny Williams and winger Jerome Thomas have all returned to training.
The team news will be confirmed at 2pm here and on our official Twitter feed @whufc_official where you can join the conversation using the hashtag #CPLWHU
West Ham have not won on any of their previous six visits to Selhurst Park dating back to a 3-2 Division One victory in September 1991, when Mitchell Thomas, Mike Small and Trevor Morley got the goals for the visitors. Palace, of course, also edged the Hammers out 1-0 in the 2004 Division One Play-Off final in Cardiff a decade ago.
