If that does happen, Chelsea will indirectly make a major overhaul again, which in my opinion will clearly disrupt their stability due to the adaptation of new players.
I think instead of that happening it is better to focus on looking in the defense area first. Chelsea's midfield and attacking line are actually very good and it shows when their mastery is good and the most important thing for Pochettino is to restore the performance of some of their strikers to score goals.
Palmer is always good at finishing but when there is a lot of guarding on Pamler then other strikers like Mudryk are quite stuck and this is what Chelsea must pay attention to.
Sterling is also not maximized well so there must be a good scheme for them to go according to plan rather than constantly reshuffling players who make this new again and again.
It's true that Chelsea doesn't need a major overhaul because the current squad is sufficient and able to compete it just needs a few adjustments, if they really want to bring in new players it's better to focus on the defense line because Chelsea's defense is one of the weakest at the moment with a record of conceding 26 goals in 16 matches yeah that means the average Chelsea conceded 1.6 goals in each match of course nothing can be relied upon with it. Previously I was optimistic that Chelsea could rise from adversity but after their recent losing streak that optimism has disappeared.
Chelsea still has time to improve everything in the next transfer window It's just that is the owner still willing to spend a lot of money to bring in new players? We know that in the last 2 seasons Chelsea has spent a lot of money of course they don't want to repeat the same mistake.
