Tuchel does have a tendency to burn his bridges after a couple of years, but I don't know that he's primarily to blame for his sacking in this case. Chelsea is a real meat-grinder for managers, and the transition over to Todd Boehly's ownership and removal of their previous DoF have made a normally tumultuous club even more unstable. Still, Chelsea have not gotten particularly great results since the second half of last season through the present, and their summer transfer window was... not great. I get some Ed Woodward vibes from Boehly, so best of luck to whoever takes that job.
I read that Graham Potter was granted permission to speak to Chelsea about their new opening. I pray he doesn't take it. Chelsea is a manager's graveyard, and he's got such a good thing going at Brighton right now — it would be a shame if he didn't stay and see it through at least this season.
I loved Keane as a player (he was an SOB, but he was our SOB!), but have little time for him as a pundit. I assume most ex-players are instructed to be caricatures of themselves on camera to garner attention, so I tend to get my football analysis elsewhere.
