I think realistic with Chelsea's fans expected with their manager Pochettino giving any tittle for the first season after spending much money and make huge rotation players after sacking many senior players. Its problem for Pochettino not trust yet any senior players in squad and replacing by youth players has higher transfer market values but get inconsistent performance, actually too fat comparison between Jose Mourinho and Pochettino how difficult with Chelsea break to top fourth standings position in this season although become most much money spending recruit new players as Premier League teams.
Seems still has second chance for Pochettino in next season will make Chelsea more competitive to get top fourth position standings or not any change yet with Chelsea performance keep difficult raise to Europe League and Champion League spot place.
Chelsea still needs a process to be truly stable in terms of performance, with last season having made a lot of player changes, it is not easy to be able to compete in the EPL. But if the fans are a little patient next season the results could be much better than now. As a fairly well established English club, Chelsea in the hands of Todd Boehly, has many procontra. The transfer and player purchasing policy is considered a failure. Todd doesn't understand Chelsea cycle so it's not surprising that this season the results are a little unexpected. However Chelsea is still facing the end of the season and can still have a positive impact and is now in 9th place, slowly rising. Last season the Blues were only able to finish in 12th position in the standings, while this season there are still 6 matches and if they are able to finish with 3 points, it is possible to overtake Man United in 5th position.
But the problem is that fans are not satisfied with what he has shown this season. The fans definitely want to get better results than now, so it's natural that they doubt the performance of their current coach. This is nothing new, even with teams that can only compete in the top 5, there are some fans who don't like their coach because they think their team can show more than that.
However, Chelsea also have to consider it carefully, because in the last few seasons they have changed coaches several times, and in my opinion this is not a good thing. We can see their decision when they fired Thomas Tuchel at that time, even though their performance was actually not that bad. But when they made the decision to sack Thomas Tuchel, they had even worse results. they must be able to learn from their experience, because there is no guarantee that when they change coaches they will be better, although there is also no guarantee that when they retain their coach, they will improve even more.
