I don't think anyone is disrespecting Chelsea. It would be foolish when they're at the top of the table. However, they were handily beaten by City. At the same time, I don't think it's unfair to say that Liverpool's best 11 is probably better than Chelsea's. I also don't think it's unfair to say that I like City's depth, manager and overall group more than I like Chelsea's. I also don't know that there's a lot of comparison with the backlines between Chelsea and either of Liverpool's or City's. It's also not unfair to say that in all likelihood, the two best teams in England right now, played on Sunday. I think Liverpool up front, and in the backline, are significantly better than Chelsea.
Yet, Chelsea have to be considered in both the title and the CL. I don't think a side with a fully functioning Kante should be underestimated. In any one off match, they're going to be in the match because they do have some really great players.
