Speaking to Prime Casino, Waddle said: "What is he doing at the minute? They said he was ill for the Liverpool game, not in the squad. No disrespect, but he's not young anymore. People keep talking as if he was 21. He's not. He's had an in and out career. We all know he's got ability, but we’ve seen this story with so many players before.
"Players like Dele Alli, Ross Barkley they come on the scene, burn brightly and then disappear. Both of those players were talked as world-beaters when they were younger, and they couldn’t do it over the curse of their careers. There are so many players who were tipped to become the next big thing, and it didn’t happen for them."
