FC Barcelona forward Luis Suarez believes the La Liga champions must a look at their performances following a second defeat of the season.
Goals from Ramon Azeez and Alvaro Vadillo confirmed Granada CF's 2-0 win over Ernesto Valverde's side, and the Uruguayan was clear in where the blame lies for the defeat.
"Tonight was a worrying defeat, and it hurts a lot.
"There were many things that we did not do well and we must be self critical.
"If we want to improve we have to look at ourselves and where we are going wrong."
Suarez, who made his first La Liga start since the opening day of the season after recovering from injury, but both he had Antoine Griezmann struggled to create chances -and the former Liverpool man acknowledged the issues in attack.
"We have to look at how effective we are in front of goal.
"We had a lot of possession, but created very few chances.
"We know there is a responsibility to winning games at FC Barcelona, and we need to be more decisive if we want to win the league."
