Lionel Messi’s second-half strike against 10-man Granada gave new coach Quique Setien a winning start at Barcelona, but it was not a convincing display by the La Liga champions.
Barca had more than 80% of the possession, but the build-up was often slow and ponderous at the Camp Nou.
Setien’s tactics for Barcelona’s attack was to try to go through the middle of the backline, but more often than not they were suffocated by a well-drilled defence.
That defence lost a man when German Sanchez was shown a second yellow in the 69th minute for a foul on Messi, and seven minutes later Barcelona were ahead.
The home side persisted with the tactic of going through the middle as the Argentine linked up with Antoine Griezmann; he found Arturo Vidal, whose drag-back teed up Messi to stroke home.
