#2 Experience
Jose Mourinho knows what it takes to win the English Premier League, he has done it three times before with Chelsea. In addition, he has balanced European campaigns with title challenges and knows how to implement a title-winning mentality into his squad. Add to that know-how the fact that he has also won league titles in Portugal, Spain and Italy, and you appreciate his understanding of how to manage a long and hard domestic campaign.
Of course, Guardiola has also enjoyed domestic league success in Spain and Germany, but these are very different environments to the English Premier League, and also Serie A. Guardiola's Barcelona had stiff competition from Real Madrid and Atletico, but the team inspired by the likes of Messi, Xavi and Iniesta were unique.
Meanwhile, Bundesliga success is expected as the bare minimum requirement at Bayern Munich, and while Guardiola claimed three consecutive league titles in Bavaria, he was only judged on his lack of Champions League success.
