Wouldn't agree with that. Would say its very similar and arguable either way, but a front 3 of Werner, Ziyech and whoever their 3rd attacker is vs a front 3 of Martial, Rashford and Sancho? I'd take ours. Midfield of Bruno and Pogba vs any 2 of theirs (Kovacic/Jorginho/Havertzin that situation), I'd take ours. Holding midfielder with Kante they have it, but he's not what he was and McTominay is always improving. Defensively we are a much better side all around and have shown it this season, and while Chilwell would be a good signing, they'd still be open.
They'd have a good squad, but one that would require a lot of gelling to the league and to each other which is never a guarantee. If we only add Sancho, we're looking pretty complete already, while its a much more seemless transition with only Sancho being added to a clear spot in our side, with the rest already gelling together (still to see Pogba with Bruno of course). Anyway, the best 11 doesn't always win. Both us and Chelsea would have squads capable of challenging with City and liverpool, but Klopp and Pep are that much better that they'd still likely dominate (for now).
