I don't see why everyone is so complementary over them. Sure, they've had a stellar start to the season but in all honesty the prem's levels at the moment are pretty low. If the played barca tomorrow I'd still expect them to be in for a spanking.
Until they start playing with a proper 3 man midfield I don't think they'll ever match up to Europe's elites. Plus their defenders are pretty mediocre on the ball which means they are vulnerable to being pressed.
The money the spent on KDB, Otamendi and Sterling was ridiculous too. Yeah, sterling gives them pace wide, but that pace in a forward line us useless if its not married with productivity. KDB gives them something I guess, not sure what it is exactly. Toure still can't defend. Hart still can't kick. They are wrongly still not using Bony. In the prem where they can rollover teams, this stuff works, but it won't make you one of the best teams in europe.
We saw chelsea with a similar fast start last season and PSG made them look amateurish when they came into town. What I don't understand is how a club with so much resources can't exactly pin point where their issues are.
