I'm a bit more concerned after that. I can't really see a reason for not playing our strongest XI. Our next game is in 9 days. Europa and FA Cup are our best chances of making Europe next season. If he was experimenting/tinkering, that itself is crazy.
If he thinks that's how he thinks his system works best, with no width, two inverted WBs and favouring Mainoo out of position at #10 vs Garnacho then it doesn't feel like we'll improve even with Dorgu. He's weirdly dogmatic about the formation but then almost everything else seems like he's rolling the dice - whether he wants defenders or attackers at WB, whatever profile of #10s we play and as of last week whether we play with a proper striker. And he seems to change his thinking half to half, so it's not like an opposition thing.
Reminded me a lot of 2015/16 that game. Goalless drab first half, then imagine Garnacho was first season Martial and Maguire was Fellaini.
