"Must win" or what? Ruben has 2 more games to save his job?
He's come in a quarter way through a clusterfeck of a season, trying to implement his own system with a hotch potch motley crew of a squad, none of whom are "his" players, a squad that struggles to score goals and defend set pieces, and now he "must" win a game against one of the most in-form teams in the league!
This season, in the league at least, is a write off. This is all about Amorim learning about which players he can trust to learn play in his system and which players need to be f**ked off. We're gonna get some good results like last week in the Etihad but we're also gonna get some bad results like Forest at home a few weeks ago and very possibly Bournemouth at home today.
Maybe he could go safe for the rest of the season, revert back to a system the players are more familiar and comfortable with and we might eke out a respectable 6th or 7th place finish, and it might even give him a better chance of winning some games like today. But it won't do him or us any good in the long run because he'll learn f**k all about the players he has, and it'll be groundhog day again next season.
