The striker is unsure how the inexperienced members of Roy Hodgson's squad will handle the pressure at the World Cup but feels the talent is there.
Roy Hodgson has picked the inexperienced likes of Luke Shaw, Ross Barkley and Adam Lallana for the 23-man roster for the tournament in Brazil.
Although Rooney feels this is the best national team he has played with since his debut 11 years ago, he is unsure how the more inexperienced members of the squad will handle the pressure when they meet Uruguay, Italy and Costa Rica.

"This is the best England squad I’ve ever been involved with," he told the Daily Mirror. "The one weakness is that we have a lot players who haven’t got any real experience of tournament football. I don't think anyone can predict what will happen to England in Brazil — and that’s why I am really excited about this World Cup.
"I've got absolutely no idea how we are going to perform. We could have a massive impact on the tournament, go all the way to the final and surprise everyone. All I can say is that the potential and quality we have got in this squad is really exciting. I look at lads like Daniel Sturridge, Luke Shaw and Adam Lallana and I can’t help but be positive about what we can do.
"It’s mad because we’ve got so many good young players. When I look back at Euro 2004, I was the youngest player in the squad, but I was able to call on a lot of top experienced players to help me through. So, it will be up to the likes of Steve Gerrard, Frank Lampard and myself to pass on our knowledge of playing in these tournaments to the younger lads."
Rooney had severe injury doubts ahead of each of his previous two outings at a World Cup but there are no such worries this time around and the striker is keen to prove himself on the world stage after disappointments in Germany and South Africa.
"After the injury problems I have had in the buildup to my two previous World Cups, I really hope this can be my tournament," he said. "I haven’t scored at a World Cup yet and and that’s something I want to put right because it does wind me up. I want to do better this time — not just for myself but because I know that if I am playing well, then I’ll be helping the team."
