Definitely, Manchester city can win matches without Erling Haaland even without Kelvin De Bryune because Pep Guardiola has built the club such that the absence of any key player may not really affect the club because all the players are perfectly doing well in their various positions and considering the fact that they also have quality substitute that can also stand as replacement if some of the key players are unavailable for any match and they can do quite alright.
