Jose Mourinho has a comment or two up his sleeves and he has delivered some harsh criticisms of fellow professional coaches even when they were not worth it.
The 'Special One's trophy gallery somewhat gives him the licence to be proud, but the former FC Porto manager has thrown jibes tearing into his colleagues sometimes.
Here are four coaches Jose Mourinho probably hates from the comments he has made about them over the years;
1. Arsene Wenger: One of - if not his most hated rival. The pair have traded words over the years with Mourinho calling the Gunners boss a specialist failure while Wenger replied, referring to Jose as stupid and disrespectful.
In terms of head to head record, Mourinho sits way atop over his great rival. There are reports that Mourinho had once threatened to break Wenger's face outside the pitch.
2. Rafa Benitez: For many fans, this rivalry has reduced given the leagues and team's they both coach. Benitez finds himself at Newcastle which play in a lower tier in England, while Mourinho is aiming to return Manchester United to old glories.
Before all the coolness, it is worth nothing these two have a history.
Mou wanted the Liverpool job in 2004, but Benitez was appointed, with the latter leading the Reds to European glory after defeating Mourinho's Chelsea in the semi-final via what the Portuguese called a ghost goal from Luis Garcia.
After Mou left Chelsea on 2006, he joined Inter Milan in 2010 and Benitez replaced him, with the duo regularly discussing their trophy hauls in the media.
Benitez moved to the Blues in 2013 and led them another European glory (Europa League) and also Real Madrid in 2015, two years after Mourinho left them in 2013 which led to the Protuguese claiming Benitez was following his career path.
It is safe to say the Spaniard has a better head-to-head record against the 'Special One'.

3. Pep Guardiola: At the turn of the 2010's Mou and Pep became enemies despite being friends during their time at Barcelona. Why are the close friends now enemies?
Firstly, the Portuguese tactician was passed over for the Barcelona job and Pep was appointed, secondly Mourinho's Inter Milan defeated Pep's Barcelona in the now infamous Champions League semi-final who were seen as the best in the world at the time.
Though the duo have never directly called out each other's names in dissing the other, they have questioned the other team's abilities.
The head-to-head record suggests Pep is the better coach of the two.
4. Claudio Raneiri: For those who do not know, Mourinho was the man Claudio Ranieri was sacked at Chelsea in 2004.
Meanwhile likes of Frank Lampard and Claude Makelele were bought by Ranieri and Mourinho used them to win Premier League titles in his first season at Stamford Bridge.
Below was what Mourinho once said of Leicester City boss during his tenure at Inter Milan: "Ranieri? I guess he’s right with what he said I am very demanding of myself and I have to win to be sure of things.
"This is why I have won so many trophies in my career. Ranieri on the other hand has the mentality of someone who doesn’t need to win.
"He is almost 70 years old. He has won a Supercup and another small trophy and he is too old to change his mentality.
"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."
Despite all these comments, Ranieri remained gracious of Mourinho and kept on praising his pedigree.
Giving that Leicester City's 2 - 1 win over Mou's Chelsea in December 2015 sealed his Chelsea fate, it safe to say the Italian has had the last laugh.
Bonous...Carlo Ancelotti: Though these two do not have a direct rivalry, Mourinho said the following of Ancelotti who has coached Chelsea and Real Madrid: “Many coaches have won it more than once but there is only one club that was leading 3-0 in the final and managed to lose it. [Sir Alex] Ferguson has also won it twice. He is 68 and we’ll see how many I have bagged in 23 years.”
Ancelotti has the trophies to boast of a great coaching career and in his reply, the Italian said Mourinho was disrepectful...just like Wenger.
