The Chelsea star was speaking after bagging the winner in the Three Lions' 2-1 friendly win over Brazil, just their fourth ever victory against the Selecao, with the Arsenal youngster starring at the heart of their midfield.
The veteran told ITV: "I think [Wilshere is] a fantastic player, I've been saying that since he first broke through.
"His quality on the ball, his technical ability, his speed at getting away from people – I think he's going to be a massive player for England and in the world."
On the day when Ashley Cole picked up his 100th England cap, Lampard was making his 94th appearance and he enthused that the win over Brazil was one of his best nights for his country.
He continued: "[It ranks] very highly, it's obviously very fresh. The lads who played 90 minutes deserve a lot of credit because they can't half move the ball and they pop up in little holes behind you and there's a lot of work-rate today but we got a win.

Although Lampard feels that the win was one of the best results that he has had in an England shirt, he was less certain about it being the team's best performance of recent years.
"I don't know," he remarked, "I think we've played some very good games but probably against lesser opposition, when you play against these teams you have to work hard and be organised and I think we did it very well.
"I know they missed some chances but I think there were times when we broke on them with our speed and we could even have scored more.
"If we can continue with that attitude and get a bit more flow to our game then I think we can do very well. We can't get carried away but it's a long time since we've beaten them so it's a lovely feeling."
