I think with the recent change in performance for Chelsea, the possiblity of sacking Graham Potter will just be suspended for now. My Chelsea friends will be disappointed that Potter will be escaping the sack letter, but who knows, Potter could turn out to be the savior after all. Personally I would love to see that happen lol.
I don't know where you saw changes in the Chelsea game. These two victories that "postponed" the destruction of Chelsea are only a fluctuation in the results (they can't lose all the time - purely statistically). I think subsequent games and especially the quarter-finals of the Champions League will show whether there are real changes in the club or there is the same chaos. By the way, in the Premier League, Chelsea have a series of games ahead of them with easy opponents, but as we have already seen, they lose points even in such games.
