I don't think anyone is gonna be title challengers this year tbh. Liverpool had a significant amount of luck last year and didn't capitalise and I can't see them repeating it. City are a domestic juggernaut, to even be close to them everything has to be near perfection for you and go badly for them.
Also a few external factors to add into the mix - our new stadium would (and may still) see us get a few more points via referee decisions favouring home team (which i felt didn't seem to happen as much at Wembley). On the flip side of that, VAR should rule out a lot of home advantage decisions, at both ends, so unfortunately we might not gain as much from a big noisey home stadium as we would have done in previous years.
But just as we won't get any penalties that aren't deserved due to VAR, neither will Liverpool be able to gain points from the wind blowing Salah over in the box.
Personally think the whole league will be tighter top to bottom as a result of VAR.
