Well the same can be said about us, we buy mercenaries as well that don't give much about the club.
About spending we also spend big in the last couple of seasons. Morata, Bakayoko, Drinkwater.
The difference is that Pep gets good player while we get crap players.
Let's not even talk about how much United have spend to get where they at.
Pep is just a genius and one of the best coaches in the world. He has done great with city and brought City to a dominance force, something we nor United are despite all that money spent!
