Barclays Premier League
West Ham United v Portsmouth
Saturday 26 December
Referee: Lee Probert
Full time - And Lee Probert brings the action to a close and the players make their way off to a rousing farewell from the Hammers fans. It was tense and nervous at times but in the end the Hammers could and probably should have had more. The win lifts the Hammers out of the bottom three for now and will provide a huge lift before the London derby with Tottenham Hotspur in two days' time.
90 min - Jimenez nearly makes it three as he stings the fingers of Begovic with a free-kick from 20 yards.
90 min - We have had two of the four added minutes already. Just two more to go.
90 min - Franco is the final player to be subbed for West Ham, as Zola takes off the Mexican for Frank Nouble.
90 min - Well hopefully we have seen the last of the goals today and if we have then it will be West Ham's third clean sheet of the season.
89 min - GOAL! And that must be that. Radoslav Kovac meets Jimenez's free-kick to power a header past Begovic for his first goal of the season.
85 min - Behrami's introduction has given everyone a lift and Kovac is the next to close with rasping effort from 25 yards.
84 min - Well West Ham are going all out for the second now and a one-two between Behrami and Parker sees the former into a shooting position. Sadly he drags his shot wide of the post.
82 min - Collison could, and probably should, have wrapped up the points there but Begovic denies him. The Wales international had made his way into the area but put his shot a little to close to the Pompey stopper, who has had a great game today.
80 min - Piquionne has Portsmouth's best shot of the game so far. The forward chested the ball away from Tomkins and forced Green into a diving save with a low right-footed drive.
79 min - Grant has makes his final change with Brown making way for John Utaka.
72 min - Behrami comes on in place of Diamanti and the Italian gets a huge round of applause as he makes his way off.
68 min - It looks like we may be seeing Valon Behrami shortly as Zola has called him over. The visitors have enjoyed the better of the last ten minutes so Zola will be looking to counter that.
63 min - Jamie O'Hara is booked for a late tackle on Radoslav Kovac.
61 min - The visitors have started to threaten a bit more and Green had to be alert to rush off his line and smother the ball at the feet of Piquionne.
59 min - Diamanti spotted Begovic off his line and tried to lob him from about 50 yards. It goes a foot high and wide but certainly had the Portsmouth stopper worried.
58 min - Not much to report on as most of the action has been taking place in the midfield rather than either penalty area. Having said that, the Hammers have looked the brighter when on the ball, so hopefully they can create something soon.
53 min - Well Dindane is to leave the field but due to a substitution and not another foul. He is taken off and replaced by Nwankwo Kanu.
49 min - We have 33,686 fans inside the Boleyn Ground so not quite a sell out, but a good Boxing Day turnout nevertheless.
47 min - Only a superb save by Begovic stops Diamanti grabbing both his and West Ham's second. The winger's shot took a deflection of Finnan and looked to be looping in until he dived at full stretch and just managed to flick the ball out from underneath the bar. From the resulting corner, Upson heads straight at the Portsmouth stopper.
46 min - We are underway in the second period and Avram Grant has used the break to make a change with Nadir Belhadj subbed off for Boateng.
Half time - Great half from the home side, who go in a goal to the good. They are clapped off as they leave the field and all will be hoping for more of the same in the second half.
45 min - Collison goes close to netting for the second consecutive Boxing Day after firing inches wide from 12 yards. That would have been the perfect way to end the half.
45 min - Jimenez shows some great footwork to dance around his marker and deliver a tempting cross to the back post, but there is nobody there to meet it.
45 min - We will have four added minutes at the end of the half.
43 min - Parker has been superb again so far today. The November player of the month has run non-stop and has put his body on the line at every opportunity.
38 min - A rare shot from the visitors as Tal Ben-Haim goes on a jinking run past four players before blazing his shot well over Green's goal.
34 min - Dindane is doing well to stay on the pitch here as he brings down Diamanti with another late tackle. I make that at least five fouls this half. Probert calls him over and issues a final warning.
33 min - After a few niggly little fouls by the visitors, Collison goes close with a volley similar to the one attempted by Didier Drogba last weekend. Diamanti had played him in with a quick free-kick and the Wales international volleyed just over from the angle.
28 min - Vital interception by Faubert, who came across to flick Frederic Piquionne's pass away from the toe of Dindane.
25 min - That is Diamanti's third goal in as many games following his strikes against Bolton Wanderers and the Blues last weekend.
23 min - GOAL! Diamanti steps up and just like against Chelsea last week, puts the ball to the right of the goalkeeper and into the back of the net. How important could that goal prove to be?
23 min - Penalty to West Ham. Jimenez is tripped in the area by Brown.
20 min - Parker is in the wars a bit here as Michael Brown launches a high tackle on him. He too is carded by Probert.
19 min - Dindane makes another late tackle, this time on Parker and this time Lee Probert chooses to issue a yellow card to the Portsmouth No24.
15 min - Brief stoppage now as Mark Noble is down and it looks like he will not be able to continue. Luis Jimenez will be the man to replace him.
10 min - Good move from the hosts as Ilunga and Collison work together to set Diamanti free in the area. His low cross is hacked clear by Younes Kaboul. The best moment of the game so far.
8 min - First shot of the game from Scott Parker as tries to beat Asmir Begovic with a 30 yard chip. Sadly, if flies about five yards over.
5 min - Diamanti is caught late by Dindane and the referee has a word with the Portsmouth forward, but opts to keep his cards in his pocket this time.
3 min - Good tracking from Alessandro Diamanti, who is playing on the left-hand side of the midfield five. After taking a heavy touch the Italian slid in to block Steve Finnan's clearance.
2 min - Early corner for the visitors but it comes to nothing as the Hammers win a goal kick.
1 min - Portsmouth get the game underway and will be attacking the Bobby Moore Stand in the first half.
12.57pm - Portsmouth have not taken the usual half of the Sir Trevor Brooking Stand so we have a few more claret and blue fans in that stand.
12.55pm - It is 'Bubbles' time and the crowd, which looks to be near a sell-out, are in good voice. Hopefully they will be able to recreate the atmosphere that was here last Sunday.
12.50pm - We are in the home straight to kick-off now and the tension is building. Both sets of players have finished their warm-ups and made their way back to the dressing rooms. There was nice moment as Mullins and Jack Collison left the field together and stopped for a hug and a chat. Let us just hope the friendship stops once they are on the pitch!
Good afternoon from the Boleyn Ground.
The teams are in and Gianfranco Zola makes one enforced change to the team that drew with Chelsea last Sunday. Danny Gabbidon is ruled out with a hamstring injury so James Tomkins takes his place in the heart of the Hammers defence. There is also the welcome return of Valon Behrami to the substitutes bench. Contrary to some reports, Guille Franco is available and will lead the home side's attack once more.
Portsmouth make two changes to the team that beat Liverpool 2-0. Former Hammer Hayden Mullins takes Kevin-Prince Boateng's place in midfield, while Aruna Dindane comes in up front in place of Hassan Yebda.
