What's bizarre? Bruno is out. Van de Beek had to get a chance at some point. Antony, Sancho and Martial were out (martial finally back on the bench). He gave Garnacho a start, who is an 18 year old. So you don't put him out of position.
It's perfectly logical going with what we did. It didn't work in attack, but like... We had 4 key attackers out, so what do you expect? Take de Bruyne, Haaland, Foden and mahrez out from city's team, and you bet they'd fecking feel that. But even still, Pep has been there for a long time, and has built a squad that he could still pick from Alvarez, Grealish, Bernardo Silva. We have.... A geriatric Ronaldo who is the worst striker in the league this season, an 18 year old Garnacho, Elanga who is a championship player, and van de Beek getting a chance for the first time. Because you might as well since the others are all out.
Have some perspective. It's a loss. It happens. We hadn't conceded from open play in 7 games. We were unbeaten for 9 games. Villa just got a new manager who is a very good manager whole we had a bunch of absences. If you can't understand that we'll have some bad games now and then, let alone all things considered, then you and everyone else here losing their shit are ridiculous.
