Speaking to Eleven Sports, Lewandowski said: "I think the locker room is p*ssed off. We played a good match. It looked great in the first half, and in the second as well. Atletico created situations after our mistakes. In the last minute it was a draw, and we played as if we were losing in the final and had to score a goal at all costs."
He added: "The season is long. We had some turmoil. With a young team, jumps in form happen. We played well against Atletico, but we lost. This is a lesson for us. We missed the icing on the cake."
