I doubt any of the free transfers are cheap in terms of wages. They have come for decent contacts and a few of them at an age where its a last move (never good as nothing to prove).
JOM looked ok in flashes. I just don't think he added anything to an already plodding / side ways passing CM. We already had 2-3 like him.
You look at that Stoke squad and they have plenty of 'names' and clearly well under punching.
