Celsea should be challenging for the title next season and that's how they can get back the honor of the club. Chelsea isn't known for how they ended last season, they're known for winning. We aren't over expecting them to win the race but they should be in the conversation and be challenging other top clubs.
I don't think Chelsea will be competing for the EPL title next season, they have a lot of ground to cover before they can challenge for the EPL title again, they have a new manager, too many new players that are yet to adapt, and a 'new' hierarchy at the club that's yet to understand how football works (i consider Todd Boehly to be clueless about the beautiful game). Thus, next season Chelsea will be in the race for a top four finish, and if they can add one of the domestic cups to it (either the FA Cup or Carabao cup), then it would be a good first season for Pochettino.
