FC Bayern München manager Carlo Ancelotti revealed that injuries and a packed fixture list makes it impossible for them to play beautiful football every time they play.
The defending Bundesliga surprisingly fell behind after just eight minutes against FC Ingolstadt 04 on Saturday, but Robert Lewandowski was able to bring them back on level terms soon afterwards before goals from Xabi Alonso and Rafinha secure a nervy win.
Ancelotti admitted it was a tough match for his charges and was happy that his side were able to grind out the win.
"We are playing a lot of games, with a lot of new players returning from injury, who are maybe not yet in top condition," said the Italian. "Sometimes we need to suffer.
"We were missing a lot of players but we have a good squad. After conceding an early goal the game was difficult.
"We had problems at the back and it wasn't an easy game. We were able to equalise early and we played well in the second half and wrapped up the points with Rafinha's goal.
"It was very difficult for us. Sometimes it's impossible to play beautifully. You have to display other qualities then. The team did just that."
