Mirth This could either go really well or really badly.
I find it hard to see this going really badly, unless he suddenly turns into a crock or something. I think at absolute worst he'll be a useful if frustrating player who has a couple of fairly unremarkable years and plods off to the middle east in a few years for a reduced fee.
He hasn't lived up to his potential yet but he's still a quality, PL proven player who can play a variety of positions and even if he never quite turns into a world class player for us, will help ensure that our attacking options are more resilient and are better equiped for competing in multiple competitions.
