I'll be honest, I've never heard of the bloke, but some of the comments in this thread are laughable. People are making much of the fact that "he's not even getting a game for Southampton"
Obviously the current Southampton boss doesn't rate him, but that doesn't mean he's crap.
It's all about opinions and Koeman obviously trusts him to do a job. He signed him for Southampton and he wanted to bring him to Everton last year for a reported £2.5m but Southampton wouldn't sell.
We have now got him on a free transfer.
He may well prove to be crap, but I'll wait and make my mind up about that AFTER I see him play.
Until I get that opportunity, I'll trust Koeman's opinion and knowledge of footballers (defenders particularly) over that of cry-arse keyboard warriors who demand nothing but 'statement of intent' signings.
