Bayern Munich crushed Arsenal 5-1 in their Champions League round of 16 first leg, scoring three goals in a dazzling 10-minute second half spell to extend their record to 16 consecutive home wins in the competition.
Thiago Alcantara struck twice and Robert Lewandowski, Arjen Robben and substitute Thomas Muller were also on target as the Bavarians, inflicted a crushing defeat on Arsene Wenger's men - their first loss of the season in Europe's premier club competition.
"We have to cope with the result," Wenger said. "No matter what we say now, it's detrimental to us."
Alexis Sanchez had equalised for the visitors, scoring on the rebound after Manuel Neuer saved his 30th-minute penalty but the Gunners suffered when captain Laurent Koscielny limped off injured to leave the defence exposed.
"We played really well. The first half, the first 20 minutes, were good but we gave Arsenal the opportunity to balance the game. We had the opportunity to score the second goal," Bayern coach Carlo Ancelotti said.
"We started the second half well and we have a good result for this match but we have to play another match so we have to pay attention because in some situations Arsenal was really dangerous."
The second leg will be played at the Emirates Stadium in London on March 7.
