Upson turned out for England in their 1-0 defeat to Brazil on Saturday, and believes that troubles at club level are not bringing down his own displays.

He said: "Losing at West Ham is not affecting my performance. You take pride in that no matter where the team is.

"It is not easy and it probably is better to be somewhere where you are winning matches, but West Ham is where I am at. I have a job to do for them.

"I don't think I have made that many mistakes individually this season but we have conceded a lot of goals. That is a problem and something we need to get better at.

"I won't let that affect my international aspirations. I am at West Ham. That is my club."

something happens

As regards his future, Upson said: "If something is put in front of me, and I have to make a decision about my future, then I will.

"At the moment it is not something I am thinking about. I am a West Ham player. Unless something happens, I am fully concentrated on them."

West Ham have started to pick up more points of late, securing 2-2 draws against Arsenal and Sunderland, and beating Aston Villa 2-1.

But they remain in the relegation zone ahead of this weekend's vital trip to fellow strugglers Hull City.
