I think it's a fallacy to analyze teams based on their personnel. Yes, Liverpool have lost Mane (but they have Diaz), Chelsea lost two good CBs (but the transfer window still has 7 weeks to go), and City got Haaland who people think will disrupt their system (but does it, really?). All these sides have top top managers who can get the best out of their players and adapt their systems. Just look at what Conte did with us without pre-season and with the skint squad we had. Once we got a head of steam, we were the second best team in the league in the final third of the season.
So discount our opponents at your own peril. I think all four of us, Chelsea, Pool, and City will be top teams, who can beat each other on their day. And all four of us are better than the teams below us. The important thing will be who will be more consistent. Because, at the end of the day, we'll all take points off each other, but it's how we fare in all the other matches that will make the difference.
