Vicente del bosque column painting figure: three central defenders, a Barcelona tactics

Hello, this is my column in sina sports the ace program. Three central defenders and tactics for Barcelona, think this is my first impression of a temporary tactics, especially in the second leg against Paris, Barcelona all use three central defenders in the game, largely because of losing the first leg too much. Cruyff coaching, Barcelona's three central defenders in the two full-backs, another is the ball and the creation of central defender, Ronald koeman of great ability.
