#2 Antonio Conte
Just like he was with Arsene Wenger, Jose Mourinho was always on the back of Antonio Conte when the latter replaced him as Chelsea boss. A ‘jealous’ Mourinho started by complaining about the then Blues boss, saying Conte liked to unnecessarily make excuses about injuries to his players.
When that did not work, the Portuguese branded Conte’s Chelsea a “defensive” team and said the media never gave him (Mourinho) credit when his Blues side were playing basically the same type of football. By then, the Italian was already leading the London club to the Premier League title, having gone on an amazing 13-game winning run.
The big bust-up between both managers, though, came in March 2017 when Mourinho and his Manchester United side travelled to Stamford Bridge to face the Blues in an FA Cup quarter-final game. Around the 39th minute, Antonio Valencia went in with a hard tackle on Marcos Alonso, sparking a furious reaction from Conte.
However, Mourinho took exception to that, with the Portuguese confronting the Blues coach on the touchline. Both managers exchanged a few words, before being separated by the Fourth Official.
