I wonder what Chelsea is actually doing there, maybe the guy just wanted to nominate 4 teams he feels will win the title this coming season. But it one thing is making me laugh here is that someone said Liverpool or Chelsea will win the league. On the side of Liverpool I agree. But Chelsea should be out of that picture. Chelsea are not winning the league ahead of Arsenal and Manchester city. We are going to see a different Arsenal and Manchester city from what we saw last season. Chelsea has no chance.
I don't know if Chelsea will win the Premier League title next season, but I am certain Chelsea is a strong contender for the Premier League title next season, and if Chelsea can be consistent in winning their matches in the Premier League, I think they will have a chance of winning the Premier League title next season because Chelsea has good squad depth now.
You have said it all, their consistency is what's really going to matter in the coming season. Like I said in my previous post that all 20 teams in the premier league right now are serious title contenders. Even the newly promoted Sunderland if they are consistent in winnings their matches, they are also likely to win the premier league. After all Leicester city did it in 2016. So consistency is the key as you have rightly said.
