Manchester City assistant manager Mikel Arteta admitted the English champions were handed a wake-up call in a shock 2-1 home defeat by Lyon to start their Champions League campaign on Wednesday.
Arteta took charge for the evening with Pep Guardiola serving a touchline ban for being sent-off in last season’s quarter-final exit to Liverpool.
And Guardiola could only watch on in horror as Lyon punished a sloppy first 45 minutes from the pre-tournament favourites through Maxwel Cornet and Nabil Fekir.
Bernardo Silva pulled a goal back in an improved second-half performance, but couldn’t prevent City slumping to their first defeat of the season.
