I don't really agree with this. If we don't have enough players that are physically or technically good enough to play the new system, and/or enough time to train it properly (which are the mitigating factors regularly put forward), then why keep playing it and losing so many games?
Yes, play some boring football, get some points on the board and foster some confidence and belief before experimenting again when there's more time and an easier run of games.
Playing the one system is fine if there's something to show for it, even if we're narrowly losing but seeing improvement in some important capacity i.e. less goals conceded, or more goals being scored. Unfortunately, all we've really from it so far is increased possession, which won't win us matches.
As it is, he's won four games, two against Europa League sides that aren't great, a rubbish Everton and City who were in free fall. We've drawn one and lost the other 6. We're dropping points, not scoring many, and conceding lots of shitty goals. I'd rather switch to a boring style and maybe get some better results for a bit than to keep playing something that is ineffective and has us losing a lot.
Amorim has got an incredibly difficult job, but he's beginning to appear stubborn to the detriment of the team in much the same way Ten Hag was. Although it's still early days, I don't think that stubborness is a good thing if it's not actually improving results.
