"It's hard to think at the time and put the blame on anyone else," he said, reflecting on his performance in a 3-1 defeat to United in the semi-finals of the Champions League.
"I felt disappointed after that but I'm trying to forget about that now and this is the tournament I am in.
"I look at the season as a big success for me personally, I've got my experience in and played in some big games that I wanted to play in.
"On the other side, for the team, after what happened in the Champions League I felt disappointed, not for myself but for the team and the people I thought I had let down.
"I received a lot of support after that and that got me through it for the rest of the season. I think it showed a mental strength to come back from that, especially straight after."
