Of the two teams that are having a 32 win season from 38 games - if we call it that. Either one could do less well next season for various reasons. I find it unlikely that they will do better - or 1 team out on its own will do more than that without being chased.
I think City are slightly easier to play against than Liverpool, they give you more chance to play out if anything. Liverpool either press a lot or they sit off with men behind the ball - often according to the state of the scoreboard. Both have got too much firepower for the much less good teams - a few seem beaten before they start 90mins of defence vs attack, and lets hope for some set pieces.
Liverpool haven't been without key players up to now - even City have struggled without Fernandinho, Aguero, KDB to some extent. That's all I can see being different atm.
I think City need a striker as well, they are too reliant on Aguero & Jesus doesn't do it for me. Unless people leave, Liverpool will always be OK for goals atm.
You could argue Liverpool have peaked but City might have too. And they will want a CL at some stage too - (City).
