What's painful is that the next league game is Man City, and there's a mid-week game first.
I think Arsenal will emerge from this slump before the end of the season. But, I don't think it will be by the end of the week. If this were one of the few weeks where there wasn't a mid-week game, then maybe. Take a day out of the physical training and just try to fix what has gone wrong mentally. But, with the most consequential game of the league season coming when the team is mentally weakest, ugh. What a disaster.
