Having a look through the retained lists, there are a number of good players out of contract this summer.
Personally, I would like to sign Lloyd Isgrove, just released from Barnsley. He is a player who had great potential at a young age and it hasn't quite taken off for him yet. I think he would be a decent signing and needs to play some regular football.
Will Keane has been released by Hull. Another player who needs to kick start his career, although I imagine he would still be of interest to Championship clubs, or clubs up north.
Max Clayton is a striker who's record does not look good - but there is definitely a player in there. However, we can not risk going into a season with a striker with a poor record.
If we were to get a big bid for Eastwood, Lee Burge is available from Coventry. I've always liked him as a keeper. Possible number 2 - or would that be a waste of a budget?
Ryan Tunnicliffe has been released by Milwall. I think he has a bit of a bad attitude, but would definitely add some bite into midfield.
