next season the focus of Pochettino may only be on the Premier League. now he is still trying to choose the players he will use in the squad. Let's hope next season won't be like last season, when Chelsea threw away a lot of money but they didn't get anything.
Pochettino has a big challenge, but let's hope he can overcome it. Competing at the top of the Premier League shouldn't be difficult for Chelsea. but it all depends on how ready the new team that Pochettino will build is.
Your hopes are very optimistic, no matter how good Pochettino is, but I very much doubt that Chelsea will be able to compete for the first place, for them a place in the top 4 would be a very good result. Keep in mind that Pochettino will only start working with the team from the beginning of this season, there will be some kind of adaptation of the players to the coach, then most likely it will be necessary to correct the squard, since I doubt that all the players will be able to perform their tasks, there may be injuries and that similar. Formation of a team is a very long process, but I believe that Pochettino is able to achieve a good result with proper funding and with enough time to do so. It is also important that Boehly does not treat the team like a business, his dissatisfaction with the results is understandable, since he spent about 600 million on transfers, but expressing claims to the players arguing this with money wasted will not help improve the results.
