But the Germany international insists that points take priority over style as the Bavarians continue to adjust under new coach Pep Guardiola.
"Victory comes first, because winning is the most important thing in football," he said. "While it would be lovely to play well every week that is simply not going to happen. We cannot always shine and play to our very best, but as long as we win it doesn't matter.
"We are footballers, not artists."
Guardiola's side sits second in the Bundesliga table and trails Borussia Dortmund on goal difference, having won six and drawn one of its seven games so far.
The club faces Manchester City at the Etihad in the Champions League on Wednesday.
