Jack Wilshere admits he would have been devastated if he had missed out on the World Cup and he is raring to play his part for Roy Hodgson's England.
The 22-year-old Arsenal midfielder has not started a game since March after fracturing his foot in England's friendly against Denmark at Wembley.
But he got the nod from Hodgson and he is delighted to have the chance to represent England in Brazil.
He told The Sun: "I was nervous. I would have been devastated if I hadn't gone. But it's a great feeling.
"It wasn't a call, it was a text. I was at home, it was a great feeling.
"I wasn't fit towards the end of the season so it was a bit touch and go.
"I think the boss at England knew that - but he had been speaking to Arsene Wenger and he came to the decision that I should go. I'm delighted."
England play friendlies against Peru, Honduras and Ecuador ahead of their opening Group D game against Italy in Manaus on June 14, and Wilshere is hoping to use them to get ready for the challenges ahead.
He added: "I'm not match fit. The only way you get match fit is by playing matches.
"So I'm as fit as I can be without playing matches.
"I've done as much as I can, now I just need a few games. It's a different kind of fitness - it comes back quickly.
"If I play in a few of the friendlies, I'll definitely be match fit."
