Clement Lenglet was sent off on his LaLiga debut for Barcelona as Ernesto Valverde's men dropped points for the first time in 2018-19.
Cristhian Stuani struck twice at Camp Nou as Girona battled to a deserved 2-2 draw away to Barcelona, who saw their perfect LaLiga record end after Clement Lenglet's first-half red card.
Lionel Messi gave Barca the lead in the 19th minute and the champions looked set to collect a fifth straight league win before Lenglet was deservedly dismissed on his first league appearance for Barca following a VAR review.
Stuani levelled with a fantastic finish before half-time and five minutes after the restart the striker was on target again to give Girona hope of recording a famous victory.
