Barkuss, Berbatov is GREAT. Amauri is good. Berbatov has singelhandledly screwed Arsenal, Chelsea etc, with sheer technical genius. Amauri is not close to him, even if he can be useful for us, he would mainly be good squad player to have. While someone like Berbatov would rival Zlatan in the best creative forward in the league or one of the best ones in overall, bonafide player in every way, watching him is like watching art at times.
Something that simply shows the difference is many teams will fight for Berba, like Man U, Chelsea wanting him badly (despite their great attack), while hardly anyone will for Amauri. I like Amauri and thinks he deserves more credd then he sometimes get, but lets be realistic, he isnt comparable to Berbatov.
P.S Big bonus that Berba is one of THE coolest players in the game
