Jose Mourinho has never been one to shy away from a bit of confrontation. Throughout his managerial career, the Portuguese has had many a feud with his fellow bosses.
The current Manchester United boss just can't seem to help himself when an opportunity to mock one of his colleagues arises, and after his recent exchange of words with Frank de Boer, here's a look at some of Mourinho's best/worst ever public take downs.
6. Rafa Benitez
The feud between these two has been ongoing for years now, and if I were to list all of their jibes at each other I'd be here all day.
I will, however, list perhaps the most humorous insult directed towards the current Newcastle boss by Jose Mourinho.
After Benitez was appointed as Real Madrid's new manager, his wife exclaimed: "Real Madrid are the third of Jose Mourinho’s old teams Rafa has coached, we tidy up his messes!“
After hearing this, Mourinho retaliated in trademark fashion. "If she takes care of her husband’s diet, she will not have any time to talk about me.”
A fat joke. Real mature, Jose...
5. Frank de Boer
After de Boer claimed that it was a shame Marcus Rashford has to be managed by Mourinho, the Portuguese hit back in emphatic fashion.
“I read something from the worst manager in the Premier League, Frank De Boer, where he is saying it’s not good for Rashford to have a coach like me. If he was coached by Frank he would learn how to lose because he lost every game.”
Best not to fire shots after your time at Palace, Frank...
4. Claudio Ranieri
Even though he wore his initials on a shirt in support of him after his sacking by Leicester City, Mourinho hasn't always been a fan of Claudio Ranieri.
After replacing Ranieri in the Chelsea hot seat, Mourinho was asked about his predecessor, a question which he revelled in as he tore the Italian to pieces.
"He’s old and he hasn’t won anything. I studied Italian five hours a day for many months to ensure I could communicate with the players, media and fans. Ranieri had been in England for five years and still struggled to say ‘good morning’ and ‘good afternoon."
Ironically, however, Ranieri won the Premier League the season after Mourinho did, which is probably why the Portuguese was left to eat his words.
3. Antonio Conte
One of the most entertaining managerial rivalries in football, Mourinho and Antonio Conte have had numerous verbal swipes at each other over the years, but more recently, their exchanges have become more brutal.
After Mourinho took aim at Conte over his hair transplant and touchline gesticulations, the Italian used the phrase 'demenza senile' - which translates as senile dementia - to describe Mourinho; although it was later revealed he meant amnesia.
Mourinho resurrected the feud by bringing up a dark moment from Conte's past in scathing fashion.
"What never happened to me - and will never happen - is to be suspended for match-fixing. That never happened to me and will never happen," Jose quipped.
2. Pep Guardiola
Pep Guardiola and Mourinho never seemed to hate each other with such a passion that they did following the latter's appointment at Real Madrid.
Of course, a few jibes where taken whilst Mourinho was at Inter and faced Guardiola's Barcelona, but the rivalry went up a notch in Spain.
Mourinho questioned Guardiola's credential in Europe when he said: "I would be ashamed to have won it with the scandal of Stamford Bridge. If he wins it this year, it will be with the scandal of the Bernabeu."
Guardiola, quite clearly incised by this, hit back with: "Tomorrow at 8.45pm we will face each other on the pitch. Off the pitch he's won. He's been winning off the pitch all season. Let them give him a Champions League for it so he can enjoy it and take it home. In the press room he is 'el p*** jefe' (the ******* boss) and the one who knows more than everyone else."
The Spaniard now leads Mourinho's United by 16 points in the title race with Manchester City, so Pep may have had the last laugh...
1. Arsene Wenger
Mourinho easiest and most persistent target, Arsene Wenger has felt the full force of the Portuguese's insults over the years.
Instead of explaining the context, I'll just list the most brutal ones for you to read through and enjoy...
"Wenger has a real problem with us and I think he is what you call in England a voyeur. He is someone who likes to watch other people. There are some guys who, when they are at home, have a big telescope to see what happens in other families. Wenger must be one of them - it is a sickness. He speaks, speaks, speaks about Chelsea."
"At Stamford Bridge, we have a file of quotes from Mr Wenger about Chelsea Football Club in the last 12 months - it is not a file of five pages. It is a file of 120 pages."
"Do they know that Arsene Wenger has only 50 per cent of wins in the English league?"
"Wenger complaining is normal because he always does."
"Am I afraid of failure? He is a specialist in failure. I'm not. So if one supposes he's right and I'm afraid of failure, it's because I don't fail many times. So maybe he's right. I'm not used to failing. But the reality is he's a specialist because, eight years without a piece of silverware, that’s failure."
