I don't agree with this viewpoint at all, if that was the case they'd win it every year. They've won it twice in the last 10 years however, they "have the most money", so surely they should win it every year?
I think Pep Guardiola should get at least a little credit.
Guardiola has managed Barcelona, Bayern Munich and Man City all clubs with unlimited funds and can BUY any player.. David Moyes would have won what he has.
Judge him if he's at a Burnley or Swansea or any club without unlimited money
