If Chelsea did not win titles, people will hope that Chelsea can win titles and when Chelsea won a title, they though title it is not enough. It's so funny to see how people thinking like this, and I see this title is a good mark for Chelsea before a next season. They have been improving and this title comes to them as a result of their solid improvement in two latest seasons. It's not pure luckiness for Chelsea to go to FIFA Club World Cup final mach and beat PSG there with a very big difference.
There are no leagues as competitive as the premier league. I would not say they have the best teams but it's never a one sided season for any teams. Other leagues might get a winner weeks ahead but for Premier league, we need to wait till the last days.
Like Ligue 1 is PSG like of last 10 years, PSG won it 8 times. If we talk about La Liga, it's either Barcelona or Real Madrid, they won 9 of 10 times. For Bundesliga its Bayern Munich 9 out of 10. But if we talk about Premier League its always a competitive one.
Even if Chelsea won the largest club championship in the world, it doesn't mean they'd win the premier league.
