The trouble with Ameobi is he's as likely to trip over the ball as he is to put it in the back of the net. I love him when he scores but he's frustratingly inept at times and, it has to be said, always has been.
Lovenkrands can be a decent link up and gets himself in some good positions but he's no Sheringham, he's more like 'jigsaw' in front of goal, way too eratic.
Best is the best striker at the club atm, but I hope that changes in the forthcoming transfer window. He can improve as Ronaldo suggests, but I personally can't see him becoming top drawer.
