At least, Chelsea always starts the new season with a new team, even if it's just about changing coaches but still, with such a change of coach will make a thorough difference to the team. So yes, hopefully by always changing coaches like that maybe Chelsea still think and expect quick success. Although the reality is difficult, but it seems that Chelsea is very confident to always change coaches in the hope of getting good results. So yes, let's just look forward to whether Chelsea will manage to have a better performance in the next season of its new coach, because of course there will always be pressure that makes the results may be bad.
But with the condition that they are always new at the beginning of this season will make doubts about Chelsea remain the same in the end. Because after all in 2 seasons when Chelsea are in the same situation where the new coach is always difficult because the adaptation process is indeed slow to make the situation from Chelsea problematic and I think the conditions will be the same this season.
Not that I underestimate Maresca in this regard but on the other hand the fact that very few new coaches can immediately contribute more to a club it does happen and for this season Chelsea and Liverpool will be in a transitional situation for the start of the season which will make Manchester City and Arsenal excited because they have a good advantage for the championship competition.
The season is still quite long now and there is still plenty of time to prepare the composition of the players and the attacking schemes that will be carried out so this can be something that must be prepared from the start so that the view of Maresca becomes better.
