During an exclusive with online-casinos.com, Waddle said: "The problem with Jack Grealish is that it’s never quite clear where to play him. I don't think Jack Grealish is a left-sided winger, or a winger at all really. I think he's a midfield player who likes to get on the ball and float around and get involved. I think when he's on the wing, I don't think Jack's a dribbler. I don't think he's a winger personally. We know he can control the ball and pass it well, but he's not a dribbler. And I think if someone was going to buy him, you'd be thinking, I want him to play more as a central player, as a No. 10, rather than No. 11. Jack has got to look at whoever wants to take him where he's going to play.
"If Eddie wants him he’ll have to work out how to play him through the middle, and I think being on the wing has cost him his full potential. When he was at Villa he had a free role that suited him, and at City it’s all gone wrong on the wing. He rarely gets on the pitch, even more rarely does he finish a game he starts. He’s on the bench most of the time.
"At Newcastle or whoever buys him, they’ll need to use him as one of three in midfield, and if someone offers him the chance to play on the left again, he should make sure he says no."
