Tonks targets Portsmouth

James Tomkins wants to see West Ham United build on their encouraging performance against Chelsea when Portsmouth visit the Boleyn Ground on Boxing Day.

The central defender was one of a number of stand out players against the Barclays Premier League leaders, but knows that the performance and subsequent point will mean nothing if the Hammers let their standards slip against Avram Grant's side.

"The result will give us massive confidence for the Portsmouth game," Tomkins said. "I think the team was quite confident anyway. We showed great attitude to come and get about Chelsea, who are the top team in the Premier League. I think we can carry it on and I think we will.

"We needed to get about them as we couldn't let them play and feel comfortable on our home ground. We tried to pressure them and make them feel uncomfortable. If we can carry that on for the rest of the season we'll be alright."

Tomkins and his team-mates had a well-earned rest on Monday but were back on the training pitches at Chadwell Heath early on Tuesday. With Christmas just three days away, it is a time for relaxing and celebration for some, but Tomkins is keeping his focus only on the target of a Boxing Day win against the south coasters.

"We have had to get our legs back first as I know the lads are tired after the energy they put into their performance. I think we need to rest up and not drink too much around Christmas time, which I know nobody would do anyway. Then we can just look forward to the game on Boxing Day."

The England Under-21 international was introduced as an early first-half substitute on Sunday after Danny Gabbidon's injury and had to quickly adapt to a game that had no room for passengers.

"The game was high tempo and that's what we set out to do. We wanted to get about them so it must have been exciting to watch. I wasn't expecting to come on so early but I had to come on as Gabbs had pulled his hamstring.

"It's takes a bit of time to get into the flow of the game and it's important that I did get in because Chelsea are such a dangerous team, I'm happy we came away with something, even though we felt we got robbed a bit."

Robert Green only had one save to make all afternoon and was rarely troubled, but he could do little about Frank Lampard's thrice-taken penalty in the 61st minute. It was, Tomkins feels, a spot kick that should never have been awarded following Matthew Upson's clean tackle on Daniel Sturridge.

"I had a good view of the penalty and I even spoke to Sturridge after and he said that Matty had played the ball, so it's a mistake from both the linesman and the ref as the linesman can help him in those sorts of situations."
