The question to ask is whether you think Ten Hag has learned from the downs this season. If you think he understands why we were so poor in some games, and believe he will do better with some good additions and a deeper squad then I dont think you can make a strong argument to replace him. I can imagine many of the names touted being a disaster by october.
One aspect of injuries that people underrate is training. Even at Sunday league level, it is an absolute nightmare having players out for midweek training, then expecting them to slot in at the weekend. The upheaval has been enormous.
My own stance is that there was a worrying lack of reaction for many months there when the problem in the middle was so glaring. But people forget he was quite flexible in his first season, players were frequently dropped when out of form, and I think he got badly rattled this year, and the CL campaign hammered our confidence - it was awful. But yesterday shows again that he is a good coach, and given his developing relationship with some critical young talent like Mainoo - this is a player we could build a whole generation around - I'd err on the side of giving him another year. Nobody else is going to fix things overnight in any case. The other huge caveat is that its clear he hasnt 'lost the dressing room.' Apart from Palace, I cant remember many games where it felt like we just gave in. It felt all season like we were trying to fix a moving car and just couldnt. The break will do everybody good.
Winning the cup in this manner is brilliant for the squad, we didn't scrape by a lower league side, we beat the very best on the big occasion, and Ive said all season that we're not as far away as people think. We desperately need more ability in some key areas, and some current starters will make very useful squad players.
