He's been signed on a one-month deal. Adds a body to the 'squad' and he helped get us the equaliser today so no harm done.
A massively experienced player like that can only be a good thing to help bring through your young players in the defence.
I liked CD, he helped us through a difficult time, but at the time of leaving I thought he had detirated as a player. Two years on, surely he's detirated more. Saying that, Kanu will have someone to play bridge with, so its not all bad.
