The Scouser played with Diouf at Bolton Wanderers.
He told the Liverpool Echo: “Listen, I know there's a lot of bad stuff about him.
“And he does let himself down sometimes with what he says, and the disrespect he shows to Stevie and Carra. I'd like to give him a little clip round the earhole sometimes to be honest!
“But do you know what? He's a lovely lad and he's got a heart of gold. The trouble is, he wants to be on the telly, and he knows if he speaks about those two he will be.
“Every time he got a bit big for his boots, I would tell him; 'You were the worst No.9 I've ever seen at Liverpool!' He couldn't come back at that, so I always had one over him on that!"
