Jose Mourinho and Antonio Conte are set to renew their rivalry next season, but a former Chelsea assistant coach claims the pair respect each other now.
Their feud began after Chelsea thrashed United at Stamford Bridge in 2018, with Mourinho expressing his dissatisfaction at Conte's celebration during the win.
The two then began a war of words after that before Conte left the Blues to join Inter Milan a year later, but his former assistant Angelo Alessio claims the feud was blown out of proportion.
"They are a bit similar. They have strong characters and maybe that can be one of the reasons why they clashed," he said, according to Goal.
"I remember we beat Manchester United in 2018 and Mourinho was upset due to Antonio's celebration. They continued to taunt each other for some time after that.
"Sometimes things get blown out of proportion. There were not pleasant words between them, but it all began with a misunderstanding.
"That time, Mourinho was annoyed with Conte's celebration, but that's what Antonio always does. Everyone knows that, it was a regular celebration for him.
"They are smart people, so in the end, they cleared the air. Now they respect each other and I am sure we'll see that when they meet next season."
