I personally think that Shola is the worst player in the air (over 6') that i've ever seen, he's a fucking shambles.
Lovenkrands needs 3 opportunities to score, tends to get bullied off the ball, offside too much and rarely contributes to overall play.
Carroll looked pretty fucking awesome as a goal threat in the last 4 months of the season, I was too harsh on him. He'll make a decent premier league player, but he isn't quite the answer, yet. Then again, i won't be too pissed off with him starting next season if he can find 10+ goals.
Best and Ranger i'm not even going to bother with, they're less equipped for the premier league than Ali Dia.
