I didn't say you did. You saying spurs have a better squad than United is a given. It's like saying City are better than United.
In my opinion, it's a dysfunctional squad.
It starts with the club's talisman wanting out of the club in the transfer window. He's a consummate professional, but he basically had to settle for United due to lack of interest from other clubs in the window. He is a year older, a does not have nearly the same workrate.
Other than that, players like Fred and McTomminay are not players that should be the midfield fulcrum in a squad that has title winning ambitions. Do we even need to get started on the team captain?
The pull of the club has diminished as well. They continue to miss out on key transfer targets and continue to acquire slightly above average players. Not seeing much by way of world class talent. Is there a single player in that line up that would make it into a Man City starting 11 for instance? Probably not. Club leadership also seems to lack the necessary ideas as well.
