I remember quite well when they finished 10th the season right after winning the title under Mourinho, that was not even 10 years ago, when Leicester took the crown. It doesn't even tell the full story as they were at some point even in 17th place, worse than they ever did this season.
That was the team with player of the season (Hazard), so yeah it was pretty dire then, and they clambered right out of it.
I'd count on them getting right back on top, as soon as they fix main issues and stop trying to buy the title.
Now there is too much competition in the top and I don’t even know what place Chelsea can count on even if they solve all their problems. Tell me, what order of teams would be logical for you (first 7 places)? Let's say (I know you want it) first Liverpool, then...? Whatever order you name, those who will be in 5-7 places will be obvious losers, right? But they are good clubs. The problem is that there is no place for everyone in the top.
