Maybe, I think after Ronaldo's departure sir Alex didn't care how we won just that we did nobody was better at grinding out results playing poorly then us.
I honestly still think Pep was Fergies first choice to replace him, who better than the manager who managed to team who beat him in two champions league finals.
He might have been, he actually met Pep in person in New York to discuss this but he had already given his word to Bayern at the time. I won't be surprised if Guardiola succeeds Van Gaal here in 3 years.
