For me we need 3 players:
Hutch has to go to CB permanently. Make him and Lees the solid CB pairing for the foreseeable future.
We need a RB in the style of Jack Hunt, but who actually has a final ball.
If we spend any sort of money it needs to be on a quality, commanding CM to step into Hutchinsons role. Win the ball, break down attacks and create.
Lastly we need a winger with true pace.
