Barcelona travelled to the Estadio Nuevo Los Carmenes on Saturday knowing that three points against out-of-form Granada would see them return to the top of La Liga.
Both sides had chances in an end-to-end first 45 minutes of football, but it was Granada that led at the interval courtesy of a smart finish from Yacine Brahimi.
Barcelona had a number of chances in the second period, but could not make the breakthrough as their title challenge suffered a serious blow.
Read how it all unfolded in Sports Mole's minute-by-minute live commentary of the action below.
GRANADA: Karnezis; Nyom, Ilori, Murillo, Foulquier; Iturra, Rico, Recio; Brahimi, Piti, El Arabi
BARCA: Pinto; Montoya, Mascherano, Busquets, Adriano; Song, Cesc, Iniesta; Pedro, Messi, Neymar
7 - Lionel Messi has scored seven of Barcelona's last 10 league goals, with four of them coming from the penalty spot. Executioner.

10 - Lucas Alcaraz has lost 10 of his 11 league meetings with Barca as a manager (five goals scored, 26 conceded). Laborious.
