The Germany international is livid with Bayern Munich's lacklustre performance in Sunday's 2-1 loss and has declared the need to switch up their style of play
During the clash at the Allianz Area, the Bavarians enjoyed the lion's share of the possession and chances, but still ended up losing thanks to a late Jerome Boateng own-goal.
"In hindsight, it hurts a lot that we have lost the points at home," he told Fcb.tv.
"The fans were not happy, obviously. We have not managed to make the most of our chances despite our superiority.
"Whether the defeat is because we played badly or because we played the wrong players, it doesn't matter as we have to win these games. We have the quality in our squad, but somehow we cannot get the ball on target.
"We need to change something, play the ball differently, perhaps, or swap players' positions around. We will see what the coach comes up with."
Sunday's game ended Bayern's perfect start to the new Bundesliga season, but they stay top of the table with 24 points from nine games.
