Sergio Busquets has conceded Barcelona face an uphill battle to retain their La Liga crown after a 2-2 draw with Atletico Madrid on Tuesday.
Lionel Messi scored his 700th goal but it was not enough for Barca to claim all three points at Camp Nou, where Saul Niguez scored two penalties to earn Atleti a share of the spoils.
The draw leaves Barca one point behind leaders Real Madrid, who could move four clear with a win over Getafe on Thursday.
There are five games remaining for Barca to turn things around, but midfielder Busquets acknowledged their fate may well now be out of their hands.
“Look, to fight for the title is really complicated if you’re dropping two points each two games, but we’re going to keep fighting until the end,” the Spain international told Movistar.
“We know it’s difficult but we’re going to try. They’re a difficult rival. We dominated and created chances but the two penalties, penalised us – it’s been a real shame.
“We were leaders and in a perfect situation before the break. I think it’s been difficult for us since – some matches we’ve played better, others we haven’t.
“Dropping points today and at the weekend means we’re a little bit further away from our goal, which is to retain the title. I think we played better today but it’s a difficult task ahead of us.”
Diego Costa’s own goal from Messi’s corner put Barcelona ahead, before Saul hauled Atleti level from 12 yards – his goal coming after Costa had seen his penalty saved by Marc-Andre ter Stegen, only for a VAR check to spot the goalkeeper had moved off his line.
Messi chipped home his landmark goal from the penalty spot shortly after half time, yet Saul kept his composure with his second spot kick of the match.
Yannick Carrasco won both of Atleti’s penalties, and the Belgian – who returned to the club in January following a stint in China – was buoyed by the visitors’ resilience.
“We always want to win, but I think the team played well. It’s just unfortunate we couldn’t get the three points,” he said.
“We have to keep working and think about the next game. We were playing against one of the best teams in the world. A point away from home is always positive but we wanted to win.
“It’s the attitude which is the most important facet of this team always. After that we can win or lose, but if the attitude is the correct one then the coach is happy. Today wasn’t to be but we can be proud of our performance.”
