Barcelona striker Robert Lewandowski admits they failed to take their chances in defeat at Rayo Vallecano.

Lewandowski says they lacked calm in front of goal.

"It's always difficult to play here. We tried to fight for the three points. We lacked the composure to create more goal situations. We have to keep going and look ahead to the next game," he told DAZN.

"We are in a good position.

"We now have two home games and we have to try to play well and think about what we need to do to play better in the seven games we have left."
