Robert Lewandowski has admitted that Barcelona “forgot to defend” in a Champions League draw with Inter that could cost them a last-16 spot.

The Liga giants are sweating on progress to the knockout stages of elite European competition after being held on home soil by Serie A heavyweights.

Xavi’s side opened the scoring through Ousmane Dembele, but then fell behind on two occasions before a stoppage-time equaliser from Lewandowski gave them a continental straw to clutch.

“We had so much desire to score that we forgot to defend. We tried to attack with more players so that one of us lost coverage.

We scored three goals but we conceded the same. We feel disappointed not to have won. We lacked cold blood and calm.”

Lewandowski added on the challenges being faced by the Blaugrana: “We’ve had a lot of injuries to the team in the recent weeks, it’s not easy to change the line-up all the time. We lack stability.”
