I agree. However, once the new management have realised that Graham Potter was not working and did not seem likely to suddenly turn a corner, they've had to act.
I think most people agree that Tuchel should never have been sacked, but it's happened, so no point in us crying about it any more.
All things considered I'd be really relieved to hear that we've appointed Pochettino with immediate effect so he can start rebuilding some trust within the squad. I suspect that many of the players are feeling nervous about there being no effective leadership at this point, and will be considering their options.
I think Boehly just tried to wave a magic wand when he arrived, instead of implementing a solid gameplan. Contrast that with Mansour bringing in Ferran Soriano and Txiki Begiristain, and I think in Chelsea and City you have two pretty good examples of how not to do it vs how to do it amazingly well.
