Antonio Conte and Jose Mourinho rivalry: a timeline of hate
Tensions between Antonio Conte and Jose Mourinho have boiled over in recent days.
It seems that no subject is off limits as the two men trade escalating public insults, and all eyes will be on the Old Trafford touchline when Chelsea take on Manchester United in the Premier League on Feb. 25.
ESPN FC takes a look back at how this level of antipathy developed between two of English football's most high-profile coaches.
October 2016 -- Mourinho humiliated at Stamford Bridge
Chelsea won 4-0 on Mourinho's Stamford Bridge return and Conte riled his opposite number by waving his arms to encourage the home fans to raise the volume for their team in the final minutes. Mourinho was reported as telling him in Italian: "You don't celebrate like that at 4-0. You can do it at 1-0, otherwise it's humiliating for us."
Speaking to Sky Italia after the match, Conte insisted he had no regrets. "I've been a player too and I know how to behave," he said pointedly.
March 2017 -- Mourinho highlights Chelsea's "privilege"
Ahead of another United visit to Stamford Bridge to take on Chelsea in the FA Cup quarterfinals, Mourinho had a simple explanation for why his former club were 10 points clear at the top of the Premier League.
"The most difficult thing to have is time to work, and they have time to work," he said, referring to Chelsea's lack of Champions League commitments. "They have time so they are in a position of privilege, but I don't want to say that they don't deserve credit for it."
Mourinho also offered Conte a back-handed compliment for his team's style of play. "They defend a lot and well, and they counter-attack and kill opponents on the counter-attack, similar to my Chelsea," he added.
March 2017 -- Conte riled by Hazard treatment
Chelsea beat United again, this time 1-0, in a game marked by heated touchline exchanges between Conte and Mourinho.
The Italian was angered by the visitors' persistent fouling of Eden Hazard that led to the early dismissal of Ander Herrera, interpreting it as a deliberate and cynical strategy. "This tactic, to play by going to kick the opponent, does not exist," he insisted afterwards. "It's not football for me."
April 2017 -- Conte belittles United spending
Shortly after a 2-0 defeat to United at Old Trafford cut Chelsea's lead over Tottenham to four points, Conte pointed out that the failure of both Manchester clubs to compete for the Premier League title proved that spending big in the transfer market is no guarantee of success.
"I think this season it's very important to understand that it's not always who spends more money who wins," he said. "Otherwise, in this league, this season the name [at the top] would not be Chelsea or Tottenham or Arsenal or Liverpool."
July 2017 -- Conte out to avoid "the Mourinho season"
Flushed with Premier League title success, an emboldened Conte revealed he had warned his Chelsea players that he would not tolerate a repeat of the spectacular collapse Mourinho presided over in the 2015-16 season.
"Two years ago, the team finished 10th place in the league and we want to avoid this," he said during the club's preseason tour of the Far East. "I want to avoid, and the players want to avoid, the last season with Mourinho."
July 2017 -- Mourinho aims hair dig at Conte
Mourinho couldn't resist responding with athinly-veiled reference to the hair transplant that Conte reportedly underwent before embarking on his coaching career. "I could answer in many different ways but I'm not going to lose my hair to speak about Antonio Conte," he said.
October 2017 - Conte warns Mourinho to stop talking about Chelsea
Mourinho poked at Conte again after United's Champions League win over Benfica. "Other managers, they cry, they cry, they cry when a player is injured," he said, referring to the Italian's frequent mentions of the key absentees that were undermining Chelsea's season. "If I want to moan and cry like the others, I can cry for the next five minutes. But I don't."
"I think he has to think about his team and start looking at himself, not others," Conte bristled in reply. "I think that a lot of times Mourinho [likes] to see what happens at Chelsea. A lot of times, also last season."
November 2017 -- Mourinho and Conte blank each other
Chelsea beat United 1-0 again at Stamford Bridge, this time in a match that passed largely without incident. The tension between Conte and Mourinho was palpable, however, and the Italian strode on to the pitch at the final whistle without looking to shake his rival's hand.
"You want me to go and chase him into the middle of the pitch?" Mourinho said when asked about it. "I was there. I shook hands with the people who were there. I think one of them was his brother, the assistant, so I feel that, by shaking the hands of his brother and the other assistants, I did my duty."
"It's not important," Conte insisted to Sky Sports. "It's important to win the game. You have to have the respect on the pitch, not outside the pitch."
January 2018 -- Mourinho makes "clown on the touchline" jibe
The latest escalation in hostilities was sparked by Mourinho, who insisted he retains his passion for football despite not acting like "a clown on the touchline" -- widely interpreted to be a reference to Conte's demonstrative style.
Conte certainly thought so, and when the comment was put to him he suggested Mourinho had a memory problem that had made him forget his own past actions. He used the Italian phrase "demenza senile", which translates as senile dementia, though Chelsea insisted he meant to say amnesia.
January 2018 -- Mourinho brings up Conte's match-fixing charge
"I don't need the Chelsea manager to say I made mistakes in the past," Mourinho responded when asked about Conte's comments, before adding: "What has never happened to me and will never happen is to be suspended for match-fixing."
Conte was accused of failing to report match-fixing during his time in charge of Siena and banned for four months by the Italian football authorities while coach of Juventus in 2011, though he was cleared of wrongdoing five years later.
January 2018 -- Conte calls Mourinho a "little man" and a "fake"
Conte did not react kindly to Mourinho bringing up one of the most traumatic experiences of his career, and renewed his attack after Chelsea's goalless draw with Norwich City in the FA Cup third round.
"In the past he was a little man in many circumstances, he is a little man in the present and for sure he will be a little man in the future," Conte said of Mourinho. "You know him very well. The level is very low."
He also accused the Portuguese of insincerity. "When he was in Italy he offended [Claudio] Ranieri for his English," Conte added. "Then when Ranieri was sacked [by Leicester City] he put on a shirt [with initials on it in support of] Ranieri. This shows you are a fake."
Conte concluded his extraordinary rant with a comment that will ensure huge anticipation ahead of next month's meeting. "It will be the opportunity [to clarify things] in the game against United when we go to Old Trafford," he insisted. "Me and him, face to face. I'm ready. I don't know if he's ready."
