West Ham defender Matthew Upson has refused to commit his long-term future to the club.
Upson's stay at Upton Park has been the subject of conjecture for some time due to the club's financial problems.
The 30-year-old has just over a year to run on his contract and West Ham owner David Sullivan has incidated the England international could be sold if he does not agree a new deal.
When asked if he was considering his future at West Ham next season, Upson told The Sun: "Not really.
"I've got a World Cup I'm focused on.
"My club form will dictate how successful I am in terms of going to that.
"I've a lot of responsibility and I'm glad of that. I want more and us to do well."
