Martinez would be free, Whelan has said he would release him if Martinez asked to leave so that makes him favourite imo, all the other external candiates apart from Pereira would require compo.

This is exactly what he did with the ****e and Villa before turning them down

He said he wants compo. 12 month left on his contract.
