West Ham defender Matt Upson admits this summer's World Cup finals is likely to be his last chance of playing on the world's greatest stage.
Upson is hoping to be named in England's squad for South Africa after becoming a fixture in Fabio Capello's plans.
The 31-year-old is happy with how he has done with England and he is excited at the prospect of playing in such a big tournament as the World Cup.
"Now I look at my recent England situation and I'm pretty pleased," Upson told the Daily Star.
"I've played several games and helped the team when I have come on.
"I'm happy with that. This is probably my last chance to play in a World Cup.
Difficult"Realistically it's going to be difficult to be performing at that level when I'm 35. So I'm 100 per cent determined to make it count.
"It has been a difficult time with West Ham this season.
"It's definitely a lot harder to impress than if the team's performing well - and I don't think I'm in the best form of my career.
"But I think I've got another level to offer and I want to be a part of the World Cup now.
"I can already feel the excitement building."
