It's honestly not.
I was one of those who were convinced that you finally got your hands on your first really good manager since 2013. One with real promise and who would get you back on the right track.
I personally chalked off the few pastings you got last season to the classic "manager adapting to a new league", especially when it's current best in the world. Martinez was a great signing, same for Casemiro even if short-term, Eriksen on a free was a coup, and Malacia a good back-up. Antony was a disappointment but you can't always struck gold. Despite what people say about your League Cup run, a trophy's a trophy and it does a starved team a world of good.
After that Cup win though... Well, you've not really been at the races. No big deal, summer's coming and a couple of new signings to build on what's been achieved last season and get things really going. Or so, you'd think.
The problem is that it went from objectively good last season, to bad, to worse, to downright catastrophic after half of a season. In fact, the more your team looks like a Ten Hag one, the less performing it becomes. His tactical changes (and new signings) managed to transform a team that was very solid at home but relatively vulnerable away to one that gets now spanked at home and away. One that could challenge for Top 4 to a mid-table one. One that now can't score to save its life and leaks goals like the Titanic.You can't defend and you can't attack. Your league table position is only due to the piss easy run you've had until now. The only convincing wins were against Everton and a Chelsea team that's been at sea for one and a half year. Any decently organized team comfortably plays you off the park, be at home or away. Finishing bottom of a CL group with Copenhagen, Galatasaray and a Bayern team far from its best is stuff of legend.
Many of you rant about injuries, and you truly have a long list, but the thing is that the players who are now injured weren't exactly pulling up trees when they were fit. You then have a manager with the charisma of a wet napkin now fighting for his life, abandoning every single principle of his, and falling out with players whilst having zero results to back him up. He has signed every player under the sun that either played for him or in the Dutch league, yet has consistently been out coached, out fought and out thought and at every single turn.
The arguments to keep EtH are exactly the same I've read here when Ole was about to get the boot. And nothing I've seen will convince me that Ten Hag's fate will be any different. He is not the chosen one, and the only thing that kept him in the job until now was the INEOS partial take-over. In fact, a defeat against Villa will more than likely seal his fate, now that Ratcliffe is officially in the game.
