West Ham United captain Matthew Upson cannot guarantee his long-term future at Upton Park.

However, Upson insists he won't seek a move from West Ham to boost his World Cup chances.

He told the Daily Star: “Whether I stay at West Ham or not is not an issue in terms of the World Cup. If I have to make a decision then I will.

“At the moment that’s not something I think about.

“Like I say, I am a West Ham player and I am focusing on what I need to do.

“If someone puts an option in front of me and I have to make a decision then I will. But at the moment that’s irrelevant.”
