Final score: West Ham United 0-1 Tottenham Hotspur
FT: All over. What was a pulsating game had a harsh sting in the tail for the Hammers. Having missed a first half penalty though Mark Noble and not made use of an extra man for 30 minutes, the game was brought back to 10-a-side thanks to two yellow cards for James Collins. Spurs debutant Eric Dier then burst through to score an injury time winner and leave the Hammers pointless from a game which promised so much.
90+3: Goal! Oh no. Spurs have won it at the death. Cool play from Eric Dier to collect the pass from Harry Kane, take it around Adrian and slot home. Cruel on the Hammers.
90+2: Kouyate goes in the book but he won't mind that one, cutting off a Tottenham break before it could reach the danger zone.
90: Now it's Spurs' time to press and Bentaleb's strong left footed shot from 25 yards needs to be beaten away by Adrian. Meanwhile four added minutes have been signalled.
88: What a save Lloris! That looks like the moment as Downing feeds the ball into Nolan's feet, whose backheel releases Downing. His first touch gives him the space the shoot, but Lloris closes him down in a flash to block away.
86: The game is becoming more and more stretched as we near its conclusion and Downing crosses from the right towards Valencia. It's over Lloris' head but has too much on it and Valencia can't quite keep it in before knocking back across goal.
84: Great battling from Valencia to force a corner down the left. Noble delivers,but it's too close to Lloris, who fists away.
82: Spurs make another substitution, with Harry Kane replacing Emmanuel Adebayor for the closing stages.
81: Stewart Downing sends over a teasing cross which Capoue has to head behind and that's Valencia' cue to come on, replacing Carlton Cole to a huge ovation.
78: Enner Valencia is stripped and ready to come on for the Hammers. He'll be coming on at the next break in play.
76: Both teams still sense a winner here and Diame is the latest to try and find it, collecting a pass from Noble on the left wing, dropping his shoulder to move inside and drag a shot wide from range.
72: Great harrying from Kouyate to win possession back and his foot in gives the ball to Noble, who knocks past his man and charges towards the box. He tries to shoot across Lloris but the Frenchman gets down to make a smart stop.
70: Spurs, buoyed by the evening up of numbers, are trying to press themselves now and Townsend's thunderbolt from 22 yards brings a good save from Adrian.
68: Adrian is not happy with Adebayor's challenge as he gathers a cross which comes in from the right. The big striker ran into the Hammers keeper and he took exception to that. Meanwhile, Mohamed Diame is on for Ricardo Vaz Te.
65: After a slight delay due to an uninvited intruder on the pitch, Eriksen blazes the free kick over the top and the Hammers take stock. Will we be made to rue not making use of the extra man?
63: It's ten men apiece now. Adebayor is given the chance to run at the Hammers defence and he's just a touch too quick for Collins, as he commits to a tackle and can only upend the Spurs man. It'a a second yellow card and both teams are a man light now.
62: The Hammers are also changing it up, with Joey O'Brien being replaced by Guy Demel.
61: Tottenham make a coupl of changes, with Townsend and Holtby replacing Lennon and Lamela.
59: It's a good job Cresswell got back to speed quickly as he has to cover round sharply to take the ball away from Lennon after Rose got away from O'Brien in the left channel to provide a low ball across the area.
57: Corner for the home side as Rose can only half block O'Brien's attempted cross. Downing and O'Brien work his short, but the former's eventual cross his overhit and it's only a goal kick to Spurs.
55: Concern from the Hammers as Cresswell twists his knee as he aims to retain possession. He heads straight to the deck and the physio is called on. It looks like only a temporary blow though, as he gets back to his feet and is ok to continue.
52: Spurs then look to launch a quick attack and Collins has to foul Lamela as he nears halfway. Clear booking and Chris Foy agrees.
52: Good football from the Hammers as they move the ball from the defensive part of the pitch to the attacking. Stewart Downing shifts the ball onto his left foot and his stinging low drive is only parried by Lloris, who recovers to flick the ball away from the onrushing Noble.
48: Kouyate is already endearing himself to the Hammers fans and he makes another strong run down the right. His cross looks to be blocked behind by Rose, but the linesman judges the ball to have come back off the Senegal midfielder and a goal kick is given.
4.02pm We're back underway at the Boleyn Ground. Come on you Irons!
HT: No goals, but a breathless opening period of the Barclays Premier League season at the Boleyn Ground. The main action came in the 28th minute with Kyle Naughton's handball and red card prior to Mark Noble rolling his spot kick wide. That came right in the middle of a strong Hammers spell, and even discounting the spot kick miss, West Ham will feel they should be in front.
42: West Ham don't stay on the back foot for long and O'Brien advances from the back to curl over a right wing cross for Vaz Te, who makes a late burst but can't find the power with his header, nodding into the ground and Lloris' hands.
40: Noble has his pocket picked in midfield as he takes a touch too long in offloading his pass to Noble. That allows Lamela to drive towards the box. He clips a pass over to Adebayor, who lays the ball back towards Lennon, whose dipping shot only just clears Adrian's bar.
36: That's a better move from the hosts as Cresswell bombs on and crosses low from the left. Cole collects, turns and looks to get his shot away, but it's blocked behind for a corner, which once again looks threatening and Spurs only just deal with it. Set plays are looking fruitful for the Hammers today.
35: Back to the Spurs defensive third and Vaz Te picks up possession just outside the box, shifts it a yard and fires well over the top. Lloris never in danger with that one.
31: Spurs head down to the other end as the look to make the most of their let off. Lamela pops up in the left channel and looks to lure Cresswell into a challenge by dragging the ball back and forth with his foot, but the left back stands up stands up well to block his route to goal off and clear.
28: Penalty to the Hammers! Nolan spins and shoots from inside the six-yard box. Naughton has his hands up and although referee Chris Foy doesn't have a clear view, his linseman flags for the spot kick. It gets worse for Naughton, as that ball was goalbound, so it's a red card and he's off.
However, it's a reprieve, for now at least, as Noble sends Lloris the wrong way but rolls wide of the post.
25: Good spell from the Hammers now and Downing is getting more and more involved down the right. Kouyate gets across his man to meet his inswinging cross with a header which slides just wide of the far stick.
23: Corner to the Hammers and Noble's delivery looks bound for Collins' head in the centre. He gets a flick on it and Vaz Te's shot is blocked. The Hammers recycle the ball to allow O'Brien to cross and Carlton Cole heads wide.
20: The Hammers force another entry into the Spurs box, and Cresswell's throw in is allowed to bounce in the box, which causes a moment of panic before the Spurs defence regains its composure to clear.
18: O'Brien and Downing combine nicely down the right, exchanging passes to give O'Brien a run to the by-line. He looks to square to Cole, but he gets crowded out at the near post, then Cheikhou Kouyate is penalised as he looks to retrieve possession.
15: Stewart Downing gets in down the right and hangs up a cross which drifts over the near-post man's head and falls for Carlton Cole, but he cannot quite get the ball under control and Spurs escape.
12: It's been a fairly even start here at the Boleyn. arguably enjoying a little more of the ball
9: We see the disappearing spray for the first time before Eriksen curls the dead ball over the wall but straight at Adrian
8: Collins clips Lennon - and the ball - but Mr Foy gives a free-kick to Spurs on the left, 30 yards from goal
7: Cross-field ball from Noble to O'Brien. Downing takes on Rose, but the full-back does well to hold him off. Goal kick.
5: First shot of the season from Carlton Cole. He knocks Kaboul off the ball, then shoots high when the ball drops back to him
4: Eriksen gets in behind on the right but his cross is sliced high behind the goal. The atmosphere is amazing!
2: Eriksen picks out Lennon on the left, whose dinked centre is headed clear by Collins.
2pm: The team news is in! Big Sam hands debuts to Aaron Cresswell and Cheikhou Kouyate, while Diego Poyet, Enner Valencia and Mauro Zarate are among the substitutes. Spurs hand a debut to young English centre-back Eric Dier, their summer capture from Sporting Lisbon.

West Ham United's 2014/15 Barclays Premier League campaign - the penultimate season at the Boleyn Ground - gets underway this afternoon with a mouthwatering London derby against Tottenham Hotspur.
The Hammers defeated their London neighbours three times last season - twice in the league and once in the Capital One Cup fifth round - and will be going for a fourth straight victory over their rivals when they lock horns at the Boleyn Ground.
West Ham's last competiive outing on home turf was also against Spurs, when an own goal from Harry Kane set the Hammers on the way to a 2-0 win, which was sealed by Stewart Downing's free-kick following Harry Kane's own-goal and Younes Kaboul's red card.
West Ham have made seven new signings since then, with five of them available against their north London rivals - Aaron Cresswell, Cheikhou Kouyate, Diego Poyet, Mauro Zarate and Enner Valencia could all be involved. Two other new boys, Carl Jenkinson and Diafra Sakho, are not available due to injury and international clearance respectively.
New Tottenham boss Maurico Pochettino will take charge of the north Londoners for the first time, with new arrivals Michel Vorm, Ben Davies and Eric Dier at his disposal.
However, the Argentine could be without Kyle Walker, who is struggling with the pelvic injury which kept him out of the World Cup, while Michael Dawson (knock) and Vlad Chiriches (back) are also doubtful.
Fans should take their seats early as Mark Noble and Josh Cullen will be presented with their Hammer of the Year and Dylan Tombides Award trophies respectively, while Sir Trevor Brooking will also be presented to the crowd to receive his Lifetime Achievement Award prior to kick-off.
