Giorgio Chiellini is against Juventus' move for Sampdoria striker Antonio Cassano.

"He would be a fifth striker and it'd mean changing the tactical system," warned an unimpressed Chiellini.

"Antonio has great quality, but he would only be reinforcing an already exceptional group with David Trezeguet, Amauri, Ale Del Piero and Vincenzo Iaquinta.

"Dealing with five strikers of that quality is fantasy football, unless of course we adopt a different system."
