Having said that, i don't think Pochettino can lead Chelsea to trophies, they will definitely bounce back to become a decent team, but they aren't going to compete for the EPL title as some people think, their goal next season should be to get themselves back into the CL and prolly win either the Carabao or FA Cup.
If in his first season later Mauricio Pochettino can do good things like what Eddie Howe did at Newcastle, it's actually an achievement, being able to bring Chelsea back to the champions league zone to become a more competitive team by being able to win a lot of games, that should be quite encouraging for Todd Boehly because the damage done to Chelsea's body was quite severe in my opinion because Pochettino didn't build a team by looking for players on the transfer market but instead had to get rid of quite a lot of players at Chelsea and choose which ones would stay and play under his tutelage, but who will be the biggest pressure for Pochettino is the news from the media if when the season has started several Chelsea matches have not shown any changes, of course, he will be in the spotlight because when he started being linked with Chelsea there were several managers who were also experienced in building a team also linked to Chelsea but he actually went to Chelsea.
The Carabao Cup and FA Cup can be good choices because of course it's not a pleasant thing to come back without a title when ending the season.
