#4 Guardiola would have gone to Manchester United
It is 2016. Guardiola has decided he has had enough of Bayern Munich. Having won the league title in 6 of his 7 seasons as a first division manager, there is no lack of suitors for him. Having managed clubs in Spain and Germany, Guardiola decides his next challenge is proving himself in England, who pride themselves on the most competitive domestic football league (supposedly).
He gets an offer from City. The offer is attractive to him, particularly since they have laid a lot of groundwork in trying to secure his services, that too for several years. But then there is a rival offer from United – who have decided to part ways with Louis van Gaal. Ferguson has openly spoken of his admiration for Guardiola in the past.
Guardiola decides the City job doesn't hold enough glamour for him. Waiting for their first league title since 1968, City would be totally out of sync compared to the two clubs he had managed till then – both giants in their respective countries with proud histories to speak of.
United, then, would be a logical choice; and the club would breathe a sigh of relief after the disappointments of the Moyes and Van Gaal eras.
