The Catalans were able to break the deadlock after their opponents were reduced to ten men
Granada defender Dimitri Foulquier has hit out at Barcelona claiming they often benefit from referee decisions after seeing his side beaten 1-0 on Sunday.
Despite being on the back foot for much of the game, Granada looked poised to frustrate the Catalans at Camp Nou only for German Sanchez to be sent off for a second yellow card in 69th minute.
Less than 10 minutes later and Lionel Messi would capitalise on his side's numerical advantage as Barcelona claimed a vital three points that returned them to the La Liga summit.
