He's heard of AC Milan so might decide to stay fit for more than three games at a time. Probably not, but you never know. I'd be amazed if they're covering his full wage.
Pound for pound, a horrible, unnecessary, risky signing by Redknapp which anyone with any knowledge of the player or football could have told you would turn out to be a failure. Still, it would mean one less overrated waste of space gone at least temporarily and only Hoilett, Traore and Fer to go before 6pm tomorrow.
