Keeping someone that barely has over 50% win rate in his managerial career so far in Chelsea? thats crazy. In fact, he only maintained 51% win rate with the club because Chelsea has a decent squad to begin with. If you let him handle a club ranging from 8th to 14th place, he would have less than 50% win rate for sure. Obviously unless Chelsea has someone better than him right now, there is no reason to boot him out yet
Anyone who expected Pochettino to stay at Chelsea after this season is either they didn't pay attention to what that guy actually presented to the team this season or they aren't a fan of the club who love mocking Chelsea and trolling their poor performance or the person doesn't watch most of Chelsea match at all. If not for the fact that Chelsea has done a lot of mistakes by sacking some coaches during the half way season, he should have left before now because I don't see any difference between him and Lampard.
They literally slept in the 10th place for weeks before they digress to where they are, win matches with a lot of attention especially when they met with Manchester City but loss what would have bring them to the top of the table and all Pochettino has to say is the team this and that, the team is trying to do this, they tried their best but every time nothing works meanwhile Palmer was there to utilize all this while but he didn't until it in the end but it was too late. He should go and never come near any English league again.
