He isn't exactly young. He's 28 and will be 29 next month. Good signing for you, however you will get annoyed by his antics. He does tend to fall over alot and will be lazy. However on his day he was the best striker in the championship. Don't expect him to be constantly banging them in, but I do wish him good luck.
A good player but with Bothroyd and Taraabt in the side fans will have to get used to the fact that for significant parts of the game you will be playing with only 9 men. Both players drift in and out of the game and with this in mind you are in danger of being overrun.
