Chelsea should be able to put trust in every coach they employ, like Ten Hag at Manchester United and Arsenal with Artata. Not all coaches are able to do a great job in just one first season, even if it is not impossible, it will be really difficult because of the adaptation process.
One season is not just enough for a coach to get the results Chelsea wants, you don’t just expect a coach to come and fix everything within a season. I never expected Pochettino to be sacked, I know he started the season poorly, but we saw how Chelsea performance improved towards the end of the season, which means if Pochettino is given more time, then he will be able to fix Chelsea. Everyone was already expecting Chelsea's performance to improve by next season, but with their new coach, I don’t really know how next season will be for Chelsea.
It's a shame that Chelsea fired him just because he failed in the first season, it seems like they don't appreciate his work in one season. I think Chelsea will be just as bad if this habit continues, they won't be as successful as before.
I felt bad when I heard Pochettino had been sacked, I never expected such a thing from Chelsea. I don’t really think Chelsea will be able to achieve anything if they keep on sacking their coach every season. At least they should give a coach more time to understand the club and arrange a perfect squad.
They keep changing coaches like selfies, no matter how experienced a coach is, it will take him a long time to understand the club. Because it is not possible to do everything at the beginning, because no matter how experienced a coach is, he has to spend one to two or three seasons to convince the team that he can fully teach his team with good experience. However, I don't support the Chelsea team changing the coach so much, the coach should be given time only if he can take the team to the top with his experience.
