Pep Guardiola has told reporters Manchester United were negative in their performance at the Allianz Arena last night, claiming David Moyes kept "eight players in the penalty box" last night.
Although United opened the scoring and wasted several good opportunities, Guardiola said after the game that United were intent on all-out defence, and this strategy made it hard for his team.
However the Bayern coach said that his team controlled the game, and he was "proud" of the performance which took his side into the semi-finals of the Champions League.
Speaking to Canal+, Guardiola said: "Our situation was precarious [with only 13 first team players fit to play], so it was not easy.
"Also, they had their goalkeeper and eight players in the penalty box, and Franck Ribery was not that good in the first half as he was in the second. But we were patient.
"I'm very, very proud of my team. I'm delighted. The players ran their hearts out today and worked really hard. This is the best part of the season and we're in a great situation.
"It is never easy against an English team with a big experience. We did it again, we are now in the top four and we will see what we can do."
Guardiola admitted that "we had a little bit of luck with Mandzukic's goal" just seconds after Patrice Evra gave United the lead, but claimed that after that "we did a good job, especially with Arjen Robben, who showed a great level. We controlled the game well."
The former Barcelona coach also praised Chelsea for their vast experience, and claimed he didn't care who Bayern get in the semi-final draw.
"Every team has their qualities. Real Madrid have a fantastic team, fantastic players. Atletico Madrid are in this situation for the first time and their fans' support are amazing, so it would not be easy to play against them.
"Chelsea are an English team, they have a lot of experience with Petr Cech, Branislav Ivanovic, John Terry, Frank Lampard and a manager with a lot of experience. Every team has their special qualities so let's wait for the draw and then we will analyse our opponent in the best way."
