Wilshere insists striker Welbeck can play a leading role in keeping England's unbeaten record intact in Estonia tonight.
He said: "The main thing for Danny is his confidence.
"I said before we signed him for Arsenal that he could play centre forward and he would score goals.
"He proved that in the Switzerland game and since he's been at Arsenal he's been fantastic.
"He didn't really get that chance for Manchester United to play at the top and be the key man, the goalscorer.
"He's got that chance at Arsenal and he's showing everyone what he can do. I wouldn't say it's the start of him - but he's really starting to grow up.
"He's the key man and he likes that pressure of being the key man. His attitude is fantastic.
"If you look through the leagues, there's not many centre forwards who give you that work rate and score goals."
