I'd think there'd be a market for a guy who's only 30 and two years removed from being a very good Premier League player. He may not be a Premier League player anymore, but some team in France or the Bundesliga, maybe Turkey, might take a shot.
He couldn't even latch on in Saudi Arabia. Maybe he's asking for a ton of money, or making some other crazy demands, and that's why he hasn't signed.
He was supposedly a key part of the toxicity of the United locker room and then had forgettable stints at West Ham and Forest.
Plus, he was just convicted for drunk driving at double the legal limit. He wouldn't get a visa here.
