Jermain Defoe says he won't be sure of a place in England's World Cup squad until his name is officially announced.
The Tottenham striker - who has netted 17 league goals this term - is expected to play a major role for Fabio Capello's side in South Africa during the summer but he told Goals on Sunday that he won't be resting easy between now and the end of the season.
"I can't take my foot off the gas and think I'm on the plane because I've played well and got a few goals. I've got to keep going," said the ex-West Ham frontman.
"I've always said getting in the squad is based on having a good season - if you've had a good season for your club, you stand a good chance of getting in the squad.
"That's all I'm doing really, focusing on playing well for my club, doing something special for my club and then just getting on the plane."
Defoe looks set to compete with Emile Heskey for a starting berth alongside in-form Wayne Rooney in South Africa, but says he will be happy to take on any role that Fabio Capello gives him.
"I started the last game so it's always nice, especially so close to the World Cup. Obviously you're in the back of the manager's mind and for me that's good.
"The games I haven't started, I've come on for second half and played the whole 45 minutes. You've still got to keep working hard and be focused and just make sure that you play well for your club and when do get out there you're ready."
The 27-year-old also sung the praises of Capello and said that with the Italian at the helm, England - who begin their assault on the trophy against USA on June 12 - have a tremendous chance of lifting the World Cup for the second time.
"He's (Capello) brilliant. He always has a laugh with the players, training's always sharp. The whole set-up is brilliant, so professional. We do everything together and the team spirit is so good.
"Everyone knows their jobs, from the goalkeeper through to the centre forwards. You know exactly what you've got to do, where you've got to be, know the movements when players get the ball which is always important at that level - and it's just about winning football matches.
"I was excited from the beginning of the season. It's massive for all the players. It's a special one in South Africa as well and something that everyone is looking forward to - and I definitely think we've got a great chance.
"People look at the group and say it's easy, but at that level it's never easy. Every game is difficult at international level.
"It's a good one to start with. I've played against America a couple of times before and they're a good side, a sharp fit team. It will be a difficult game but I think, looking at the group, we've got to be confident," he added.
