ok so i noticed between 20th and 10th position in this years premier league is separated by only 5 points that is insane shows how competitive this league is and shows exactly whyits the best league in the world. our teams may not be as strong as spains or Germanys but the cimpetition is intense. Yoy can go from pisition 1 to 5 in just a match. Long live the Premier League :)

It shows only one thing, the level of teams is very close. Before PSG and Monaco, all ligue 1 top 10 clubs were separated by less than 10 pts, does it mean they were all strong ?
EPL is the most competitive one because all teams are close in term of level, except the top 3, and maybe the best to follow if you support an English team or from a neutral position.
But its not the most dificult to win, ask Mourinho why he left Spain and why he will never go to Germany in this Bayern era.
Champions League this year will show how the top 3 teams of each League will perform. If the top 3 of EPL fail all to go far, then the league is not that good because the best teams does not play there.
If Arsenal, United, Chelsea or City wins CL, then it will be significant for the League strengh.

La Liga is not very difficult to win, if you're Barcelona. And the Bundesliga is not very difficult to win, if you're Bayern Munich.

However, the PL is difficult to win even if you're Arsenal, City, Chelsea, United or anyone else.

@tiki Which of your teams is in a cup competition has NOTHING to do with how good the league is.
