With this defeat I think the Chelsea management are starting to think about Pochettino's future. I think his arrival will bring new strength to Chelsea's young players. This defeat certainly adds to Pochettino's bad record with 3 defeats. Gusto's red card also made the match worse. Coupled with the blunder made by Tiago Silva. Some media mentioned that Chelsea's young players don't have much experience for this match and they are in progress. But with the transfer conditions that are quite expensive it should not be the right reason.
I see that with this defeat, Chelsea's chances of leaving the Premier League have increased to 1 in 51

This is a small chance, but for comparison it is 1 in 251 for United and 1 in 501 for Brighton. But at the same time, Chelsea still has a good chance of entering the top 4: 1 in 5. This is only 20%, but is this not enough for a dream?

I don't know how long the crisis in Chelsea will last or how quickly it will end, but it looks like their fans will mostly suffer.
It's quite astonishing to witness how the Chelsea authority stubbornly clings onto their current coach, rendering me speechless. I guess their authority is actually not interested in improving the squad otherwise they would have changed the coach and would have surely brought in a new coach already, but what are theu doing now! I'm certainly sure there is no way Chelsea is going to improve under this coach.
I am actually amazed that the Chelsea authority has given so many chances to this coach! I am also pretty sure that if this was any other coach managing any other club, they would have surely got rid of pretty early. I wanna say it is still not too late to bring in a new coach who will be better, still there is a chance they might actually end up in the top four if they start performing well. But they are definitely not going to perform well under the management of this coach, at the same time they will have to get someone who is going to be better and will have experience of managing big clubs.
