2. Pep Guardiola and Jose Mourinho
In runners up is the rivalry between Pep Guardiola and Jose Mourinho . During Mourinho and Guardiola’s time in the Spanish La Liga , the two were always in the media saying things that were linked to each other. This is quite normal in Spain as managers involved in the famous El Classico match never seem to get along , and this seems to have passed on to the players on the pitch. The two now battle it out in the Premier League with Mourinho managing Manchester United and Pep managing Manchester City.
