Mourinho and Costa before their relationship turned sour.

Jose Mourinho's four biggest bust-ups

Published 1 Comments

Jose Mourinho’s clash with Diego Costa could force the Spaniard to leave Chelsea in the January transfer window.

However, the bulldozing forward is not the first individual Mourinho has argued with throughout his career.

Here are four examples of when the Blues boss has endured a difficult relationship with his players throughout his turbulent, albeit successful time in the game.

Adrian Mutu

After an impressive debut campaign under Claudio Ranieri, Mourinho’s arrival at Chelsea back in 2004 was expected to herald great things for his Romanian striker.

However, his decision to land the likes of Mateja Kezman, Hernan Crespo and Didier Drogba forced the former Fiorentina striker down the pecking order.

Mutu’s time at Stamford Bridge then grew steadily worse, before he was axed for failing a drugs test mere months into Mourinho’s tenure.

Despite that, the 36-year-old enjoyed a stellar career in Serie A where he won the league title with Juventus on two occasions before the Italian club were revoked of them during the 2006 match-fixing scandal.

William Gallas

William Gallas was a fantastic servant for Chelsea but soured his reputation at the club for his antics late into his time with the Blues.

Furious at losing his place in the side to Ricardo Carvalho, the Frenchman reportedly threatened to score an own-goal if he was not granted his wish to leave.

Mourinho made the ex-Spurs defender wait for his move until the final day of the summer transfer window in 2006, where he sold him to Arsenal and received Ashley Cole in his place.

Not a bad deal for all involved.

Iker Casillas

Mourinho’s final season at Real Madrid saw him make enemies with just about everybody inside the dressing room.

However, no feud was more publicised than that with Iker Casillas, who lost his place to Diego Lopez midway through the season.

Backed by his partner-in-crime Sergio Ramos, the pair apparently formed a rebellion against Mourinho and helped force the Portuguese manager out of Spain.

Yet the decision to relegate Casillas to the substitutes bench was backed by Carlo Ancelotti, with Rafa Benitez then selling the goalkeeper to Porto in the summer.

If ever there was a player that typifies the fighting spirit of Mourinho, then it is his countryman Pepe.

However, the pair were at loggerheads amid the Casillas scandal with the defender opting to side with his teammate rather than his manager.

According to Mourinho viewed it as the “ultimate betrayal” given the way he had defended Pepe from controversies against Barcelona and Lionel Messi in particular in the past.

Maybe that’s why we have not seen the defender sign for Chelsea despite past speculation suggesting he would.
