Mikel Arteta insists Arsenal can't use having no crowds as an excuse.
The Gunners suffered a shock 2-1 loss to Brighton on Saturday.
It was the club's second straight loss in a post coronavirus world, but Arteta says his team must adjust.
"It would be difficult at home as well without fans – we are taking a big part of what makes this sport so special," Arteta said.
"It is what it is, we are playing on fantastic pitches with the same distances and dimensions, 11 against 11, let's compete and win football games, that is all.
"I think the preparations towards City and Brighton were completely different, even if we try to go in the same day.
"I don't think it is an excuse for us to use about preparation, we had more than enough in the game to win it comfortably and threw it again so I don't like to use excuses like this when we lose a football game."
