On a free, in his peak years, Prem proven, good quality player, homegrown, reasonable wages etc I'd expect most teams that are typically top half finishers to be interested to some extent. Question is would he rather play every week at an Everton/Brentford/Palace or would he be quite happy to be part of a squad at a Villa/Newcastle/ManU level that can typically offer European football and fair chance of competing for trophies. Not saying he'll be transfer target No1 for the very top teams but he wont be short of options.
