If Pochettino leaves then Chelsea will be worse, that's in my opinion because we saw last season when Chelsea made several coaching changes but none of them were successful.
Pochettino is a coach who has good qualities and this season we can see that there is slowly increasing quality for Chelsea even though at the moment they are far behind, but the positive thing is that there is development in this team so it is possible that next season they can do even better.
I hope Pochettino is retained by Chelsea, and I am sure now that Pochettino is able to make Chelsea even better, everything requires a process and Pochettino is doing that.
Chelsea are currently considering Pochettino future at Stamford Bridge, I think it is very natural Chelsea do because indeed this season Chelsea performance has been inconsistent, lucky for Pochettino in the last game they can win and make them now able to compete in the Europa League zone after Manchester United also suffered a defeat to Crystal Palace, If you look at Chelsea's game this season of course you know why the fans are getting fed up with Pochettino, Chelsea game this season is quite bad and we can even see they just make passes backwards and sideways without any meaningful goals and not make the opponent depressed.
But in the last two games we can see they play more attractive by having a fast tempo to dismantle the opponent defense and the players are starting to dare to have possession so that the opponent is a little frustrated in chasing the ball, besides that in the last two games we can see Chelsea game scheme is more arranged so that it can threaten the opponent defense at any time, We can say that Pochettino has had a bit of time at Chelsea but I think he has wasted that time only on failed experiments at Chelsea so far, so he might be worthy enough to be sacked.
