The pressure, the distance between the forwards and the defenders and Manchester City's attitude
The 3 keys by Ricard Torquemada: Manchester City - Barcelona. The game will start at 8:45pm CET and you can follow it live at www.weloba.com
1) The pressure. Manchester City don't have Yaya Touré in his squad. This makes more difficult that City can have the ball and can start playing from the defenders.
2) The distance between defenders and forwards. Barça must avoid that Silva and Nasri could receive and play easy. They are the most skilfull players in the squad.
3) Manchester City's attitude. Pellegrini must decide if he wants to attack or defends, if he wants to keep the ball or give it to Barcelona.
