Pep Guardiola took full responsibility for Manchester City's shock defeat by Bayer Leverkusen after making 10 changes.
The City boss claimed that the decision was a 'mistake' that cost his side on a night that now makes the challenge to avoid a playoff knockout game much tougher.
Erling Haaland, Phil Foden and Rayan Cherki were all summoned from the bench but could not inspire a comeback after Leverkusen notched either side of half time.
'I take responsibility but I saw them and I like everyone to be involved,' Guardiola said.
