Sheffield United boss Chris Wilder says he has spoken with Harry Redknapp about controversial trialist Ravel Morrison.

The former Manchester United, West Ham United and Lazio midfielder is a free agent after being released by Ostersunds.

He played under Redknapp at QPR and Wilder has been impressed with his attitude in training.

"He has done well," Wilder told Sky Sports News. "I spoke to numerous people including Harry Redknapp, who had him at QPR. He's got fantastic ability.

"I'm prone to a leftfield signing, it doesn't scare or bother me. We have to take little punts now and again but there is certainly a player in there.

"We're talking to his agent, we'll see where that goes over the next few days.

"It wasn't about him coming out here and being on trial because we knew about his abilities. It's basically getting to know him and what he's about, what makes him tick and how he integrates with the players. Trips like these are invaluable for that."
