Jack Wilshere insists he is not feeling jaded after his first full season of senior-team football.
Wilshere has rubbished the theory that Arsenal boss Arsenal Wenger will be upset because he has played in two successive England games -- against Wales and Ghana -- in four days.
The 19-year-old has indicated he wants to play in the European U21 Championships this summer.
Wilshere said: "I've been playing Saturday and Tuesday or Wednesday when we were in the Champions League.
"Now we are out of the Champions League, to be honest I could have played the full 90 minutes against Ghana.
"I just think the manager will be delighted I've been picked for my national team. I feel better than I ever have. I've never played a full season but I feel fitter than I ever have."
Wilshere also thinks Andy Carroll, who netted his first senior England goal against Ghana on Tuesday, will benefit from playing for the U21s in Denmark in June.
When asked if playing for the U21s would aid Carroll, Wilshere said: "Definitely. Andy has got himself a good move this year (to Liverpool) and he is progressing all the time.
"That goal against Ghana will be massive for his confidence.
"To be honest with you, it's up to him. But, if he wants to go in the summer, he should go.
"The German U21 players played in the World Cup 12 months later and that is part of football.
"You develop a lot and, if you play with players you know, you are going to play well."
Wilshere believes England can look back with satisfaction at their efforts over the past few days, with the Euro 2012 qualifier win over Wales and a much-changed side impressing against Ghana.
Wilshere said: "The mood is good. The main thing is on Saturday we got three points and then we've tried new players against Ghana."
