Nani admits Manchester United's players are down after their Champions League elimination.
Arjen Robben's cracking late strike put Bayern Munich through to the semi-finals on away goals, and Nani conceded that the post-match mood in United's dressing room was one of dejection.
"We're feeling bad because we did so well in the first half - we scored three goals and I think it was one of our best performances - so we are disappointed," he told MUTV.
"They were a bit lucky, because having one player sent off was the problem for us, it made the team a bit down. That was the difference."
