Well that's the problem, the Chelsea owner does not give the coach the opportunity to build a squad in the long term and they want to see instant results even though they must be able to take examples from the last 2 seasons and at the same time prove that money does not guarantee a team's success. If Chelsea want to build a young squad then they have to give the coach more time at least 3-5 years as happened with Arsenal and Liverpool, as we know Arsenal's performance continues to improve from season to season and I think this season is the time for Arsenal.
I'm Chelsea fan, and I've watched how my club have surpassed the struggling limits and now settled for lesser poor results. This is out of the picture and I've come to realized that time is perfectly the stable form ought to be give to these assigned coaches. But everything turn up against our expectations, we're seeing different outcome. Chelsea is elite team but everything worked smoothly during the era of Abramovic, he made good use of his players and signed appropriate talent players. Chelsea owner, Todd Boehly is impatience and have placed down the instructed maps.
Therefore, although Chelsea has a lot of money and can afford to buy talented young players but anyway, the reality is that Chelsea cannot appreciate a process. Therefore, the result is always changing the coach despite the fact that Pochettino is also slowly and giving good results. But even though Pochettino still managed to end the season in a position that was at least still good, but it still made Chelsea sack Pochettino. Thus, it will certainly remain difficult for Chelsea to become a title candidate team next season because they have a new manager, while Manchester City and Arsenal only need to maintain their good trends. But about Chelsea with their new manager, then of course they will adapt first to be able to improve the quality of the team.
