Despite Jeremie Boga's early second-half equaliser, Barcelona pulled back within two points of La Liga leaders Real Madrid after Luis Suarez, Paco Alcacer and Neymar scored along with a Matthieu Saunier own goal in a 4-1 win at Granada.
Manager Luis Enrique was forced to alter his lineup in the face of Lionel Messi's one-match suspension for his fifth yellow card of the season in last month's win over Valencia.
In Messi's absence, Suarez led the line on his own, with Neymar fielded to the left and Andre Gomes starting on the right.
