FC Barcelona manager Ronald Koeman took the blame for his side’s poor run of form in LaLiga and demanded ‘improvement’ particularly from the defence.
The Blaugrana were handed their third league defeat of the season at the hands of Atletico Madrid on Saturday to trail top spot by a mammoth nine points from tenth place.
Belgian Yannick Carrasco netted the winner in the final minute of the first half, with Koeman not pleased at the manner in which the goal was scored by Atletico.
"It is worrying," he told Movistar, as per Goal.
"For a big team, conceding a goal like this ... it can't be, because it's the 47th minute, we had the ball and then they score, 1-0.
"We controlled and we knew that it was difficult to create many chances. We had a pair and with the score 0-0, the game would have been totally different [if they had taken either chance].
"Like any coach, I am responsible for the team's results."
