Manchester United, Portsmouth, Everton and Aston Villa are all keen on signing the former non-league star.
A source close to Kightly told the Sunday Mail: “Michael signed for Wolves until summer 2009 but he’s very ambitious and wants to get on. Everton have shown an interest since he joined Wolves and Manchester United could still come back in for him. He’s waiting to see what happens and he’s going to think about it in the next few weeks.”
