Yes they have a lot of players and have also brought in some good names too. Imo Chelsea will make the UCL. I’m so sure of this but they won’t win the league. They don’t have European distractions. Pochettino have given them a sense of play and they’re bonding and finding the rhythm this preseason. They will make the CL, people are underestimating what being totally out of Europe brings in term of squad's fitness. It's three teams that one can boldly say are ahead of them.
In the next season, Chelsea cannot be underestimated with their new squad, but Chelsea just needs to focus better on a position that can bring them into the UCL next season. Because I'm also not sure that Chelsea can win the Premier League next season, but if it's just fighting for the top four in the standings, I think it can be very possible for Chelsea. With a new coach at Chelsea, they will definitely have a different spirit next season, especially in terms of trying to be in a better position.
For the Premier League next season I am not at all sure that Chelsea will be able to become champions at the end of the season. I see Chelsea have now shown changes and progress little by little, but to shift the position of Manchester City is too heavy with the current conditions, it is true that occupying the top five positions is very possible for them. Pochettino is now very serious about his work, some new ammunition has been brought in and I see now Pochettino has managed to form chemistry with his players so it is not too difficult to form cohesiveness on the pitch. Chelsea will rise soon but not for this season, but for the next few seasons when Pochettino has managed to perfect all sides in his squad.
I quite understand your position, but the situation of Chelsea can be improved by one man leading them but it can't be done suddenly and the friendly matches we see now are not the best tests of what will happen when the real season starts, so we should still be patient before we pass the judgement. I believe that Pochettino will have an impact in Chelsea as some of his recent adjustments are called for but he needs to take more actions before the season starts. I just viewed the in and out now, I don't know what his plans are but too many young players could still be an issue.
