Say Higuain is fat if you want, but he can sure score goals when given the opportunity. I won't call him a flop in big games till I see it happen while playing for Juve.
Higuain is the best centre forward currently playing around, fat or not.
And that's not even a problem: he is strong, he has vision, he plays well and, most of all, he scores basically always. Juventus couldn't have found a better one today
