Barcelona striker Luis Suarez was left frustrated following yet another slip-up in Laliga in their 2-0 defeat away to Granada on Saturday night.
The defending champions could not find an answer to the hosts' lead after just 65 seconds and conceded a second in the second half to completely take the tie away from their grasp.
The defeat, a second in La Liga this season, seemed to rock the Catalans, with Suarez saying they need to be more careful.
The loss meant Barcelona are yet to win any match on the road, following their opening day loss to Athletic Bilbao and consecutive draws against Osasuna and Borussia Dortmund in the Champions League.
“Nothing is confirmed at this stage, but these are games which give you La Liga,” Suarez said. “In other years, we won these type of games at the end or with ease,"
“We have to be more convincing and we have to be aware that this is [going to be] a tough year.”
He gave his assessment of the match, which despite dominating, could not find a way past a stubborn and well-disciplined side who are currently atop the La Liga table.
“We had possession, but we weren’t convincing. We have to analyze what happened. We’re at Barca and we have the obligation to go out and win… not to start as we did.”
The loss saw them drop to seventh on the table on seven points, having won two, lost two and drawn once.
They next host Villarreal at Camp Nou in midweek before traveling to Getafe next weekend.
