They should improve themselves because if what was shown the previous season continues then it will be a waste of money that was spent last season and the season that will soon start, maybe they will not immediately challenge for the championship but are targeting to be able to finish in the top four, and what is it will also benefit Chelsea they only need to focus on all local competitions because there is no European competition they will play, if Pochettino is able to build Chelsea quickly what is targeted will be possible to achieve, but before the season starts it is impossible to say they are improving because of what they are doing at the moment this is just preparation to be better.
Yes, of course, they don't want this to continue, because, after all, The Blues have a goal to get the title they always wanted. New quality players have been successfully brought in and of course, Todd has spent a lot of money in the hope that his team will be able to return to better form, being able to compete in the top five Premier League standings next season is very good for the start of his struggle. Various reforms have been made for Chelsea and I am sure that the new coach this time, namely Pochettino, will not waste any opportunity in every condition, I hope that there is a match between Pochettino and the players in forming a game strategy and hopefully, Pochettino is the right coach for the situation Chelsea now.
