No one's criticizing David, it's just my opinion, that a beast like Amauri is better suited for the 4231, he hold's up the ball better and while his header may be not so precise, he still connects to way more balls than Trez because of his strength. But today that wasn't our problem, today we had Poulsen and lazy Melo (later Tiago) in the center of the pitch + Cannavaro and Chiellini played their worst game of the season thus far.
