Belotti looks like an absolute superstar. Just an excellent striker all around. What are his weaknesses exactly? Outstanding in the air, powerful dribbler, strong as an ox, amazing awareness (always knows where the ball is, where the goal is, how to get there), uses both feet (even to score), and speaking of scoring, he can't stop doing it.
I don't watch him over 90 minutes that often, but from what I've seen, a good many of his goals come from doggedness and workrate to boot.
