Whether Guardiola's absence from the dugout was behind City's ragged first-half display is hard to ascertain, but the team produced their worst performance for months while he was not standing in his technical area. We will try to reduce the impact and give the players what they need and hopefully it will work well.
City's Brazil midfielder Fernandinho coughed up possession in the build-up to Lyon's first goal, and then did exactly the same under pressure from Fekir for their second.
Guardiola has been trying to guard against complacency but Arteta insisted his side were fully aware of how unsafe Lyon were, despite their poor start to the season, which has seen them win two and lose two of their five opening Ligue 1 games.
Elsewhere, Benfica host Bayern Munich as they meet for the first time since the German side won 3-2 on aggregate during the knockout stages of the 2015/16 competition.
"We have a very young squad, but they gained a lot of experience in the last two years with the different things that have happened in the Champions League and we feel we are better prepared".
The setback on Wednesday night leaves City at the bottom of Group F, although a 2-2 draw between Shakhtar Donetsk and Hoffenheim means that Pep Guardiola's team are just a point adrift of second spot. The reality is Pep wasn't here and we lost the game.
Pressed further on how close he came to getting the Arsenal job, Arteta continued: 'I didn't talk on that moment two, three months ago, and I didn't make any statement, and I don't think today is the day to talk about it.
"I think that is a good point because we discussed it at half-time and before the game as well".
