City just too good

City won the league by a 100 points for a reason. They are just too good.
Pep is arguably the best manager in world football.
Aguero, Silva, de Bruyne, etc. are prime world class players. Sterling, Mahrez, Fernandinho, Jesus, Walker, Ederson, etc. are likewise top quality.
United have great players too, but Guardiola has taken City to a new tactical level, which United are behind in some distance.
So maybe Mourinho needs to be cut some slack? Who knows? What is apparent though is that Man City are playing at an exceedingly high level, and arguably at this state are the greatest ever PL-era team.
Mourinho did finish second to them last season, and this is no disgrace, given City's advanced development stage. So maybe the issues cannot just extend to Mourinho's supposed incompetence and/or issues with the players.
