Assistant coach Mikel Arteta refused to use the absence of Pep Guardiola as an excuse after Manchester City suffered a shock loss to Lyon in their Champions League opener.

City boss Guardiola could only watch from the stands due to a touchline ban as City were beaten 1-2 at the Etihad Stadium. The hosts were punished for mistakes as Maxwel Cornet and Nabil Fekir struck in the first half and they could not recover despite being given a lifeline by Bernardo Silva after the break. Asked if City's performance might have been different with input from Guardiola, assistant boss Arteta said: "I have no idea. That's something hypothetical. The reality is that Pep wasn't here and we lost the game. If he would have been on the touchline I couldn't say if we would have won 5-0 or lost 0-3."
