The issue is partly the players. Let's be honest, everything is wrong and all areas of the club are equally culpable. The ownership is a disgrace, the players aren't very good but the manager is also setting up to fail. You cannot genuinely tell me that there is any intention to win games of football under Amorim and certainly not last night either.
The only option is not just Southgate though, is it? It's jumping to the worst possible conclusion (though y'know, is it as bad as a one dimensional clown with no plan a who is happy to lose game after game with a wholly unsuitable bunch of players playing a wholly unsuitable style of football with no plan b for when the inevitable, conceding goals, happens?).
Amorim will be lucky to get 4 or 5 games, let alone that many years. The comparisons to Klopp are baseless and fanciful. The style doesn't work even for those who are going to be at the club next season, there's almost no signs of any player taking to the formation and there is no signs of improvement, those that were there when he took over have been washed away with his stubbornness.
The one thing you cannot accuse Amorim of is pragmatism. There is nothing sensible or realistic about the way in which he has this group of players playing. As much as they are not very good and many should leave, they're being hung out to dry in a formation and tactical style that is wholly unsuitable. Sending out Casemiro and Eriksen to be overrun by Tonali, Bruno and Joelinton was ridiculous and I think even Stevie Wonder could have seen what was going to - and did - happen.
At what point does points take priority over 'style' because there will be a time where that is needed (if it isn't at that stage already)? The system isn't working, that much is clear, why are we persisting with it for five more months? Those that are out of contract and likely to leave aren't taking to the system, those many want to be sold aren't and those that people want to remain, barring probably Amad, haven't either. You're looking at realistically needing 25 players to come in to possibly get the system to work.
