LAURENT KOSCIELNY admits Arsenal failed to ‘stay together’ as they were humbled by Bayern Munich.
Arsene Wenger’s side were thrashed 5-1 at the Allianz Arena in the opening leg of their round-of-16 clash with the Bundesliga champions.
Four of the German side’s goals came after captain Koscielny had been forced off with injury soon after half-time.
Three goals in a ten-minute spell in the second half effectively killed the tie, with Gunners manager Wenger branding the defeat ‘a nightmare’.
France defender Koscielny’s assessment was similarly damning. Asked what went wrong, he said: ‘I don’t know either.
‘I think the first half was good — we were deep, like you need to be, and tried not to give them space or opportunities to score.
‘You need to stay together and defend together as a team’’
‘It being 1-1 at half-time was good for us but after we conceded the second goal, I think we needed to stay more compact because we have a second leg at home, when you can win.
‘You need to stay together, defend together with all 11 players and keep this [scoreline]. Tonight we didn’t.’
Despite the second-half capitulation, Koscielny insists his team will not approach the second leg at the Emirates Stadium on March 7 as a dead rubber despite facing a four-goal deficit.
‘In football, you never know,’ added the 31-year-old.
‘We are professional, we have a second leg and we will try to win. But after a game like this it’s very difficult. But we’ll fight because we are professional and we play for Arsenal.’
