You don't think having the best group of players is an explanation for winning the league?
We don't... at least not according to most neutrals.
Is Ederson the best goalkeeper in the world? Most people wouldn't have him in their top 5. Certainly very few think of him as the best in the league.
Walker? People think he's a disaster. Zinchenko? Forget about it. Nobody talks about him and those that do think he's just a kid playing out of position.
Everyone knows Mendy isn't even top 20 left-backs in the world either, and Cancelo is famously poor defensively.
Ruben Dias and Aymeric Laporte were both little-known in England and Dias was said not to be good enough for the Premier League (until people watched him play). Don't even get me started on Stones... and by all accounts Aké is a waste of money.
Rodri? Do most people in England even know who he is? I certainly never hear him discussed, let alone praised. City fans love Bernardo and Gundogan but until this season what other PL fan would be that enthusiastic about either? Certainly neither were considered top class midfielders.
Foden isn't as good as Greenwood according to a thread on this very website, Mahrez is considered a top-tier winger by absolutely nobody, not even myself, and neither Jesus nor Ferran Torres come up in conversations when you talk about the great forwards of world football. As for Sterling, well, he might be the most criticised player in the world. Certainly very few people actually think he's more than a "tap in merchant".
It's fascinating to me that our players are only really praised when people want to downplay Pep's achievements, because when you look at them individually only Agüero and De Bruyne have been considered one of the world's best in their position for more than a year.
