Lampard, who is set to join MLS side New York City after leaving Stamford Bridge, can see a real comparison between Barkley and Rooney as a youngster.
The Everton man impressed for England on Wednesday night against Ecuador and Lampard can see the 20-year-old going on to make more waves in the World Cup this summer.
“There’s a lot of similarities in there, in their build, where they come from and where they play,” Lampard said. “You can’t deny that.
“Again, it’s that fearlessness of youth. I see the similarities: great ability on the ball, running at people with the ball, and that’s what you want to see.
“I think he’s got the bit between his teeth. He’s more number 10 than I ever was but he’s very good at receiving the ball and turning quickly.
“He’s only going to get better. That’s his first start so considering that when you look at him and what he’s done, he’s made the second goal and shown enough there that we can say that he deserves his place in the squad and he’s a great addition.
“We go to Brazil next week and hopefully he’s going to be confident which is great.”
