The two managers have continued to snipe at each other since then, but their comments have acquired more bite lately, beginning when Mourinho implied that Conte was a "clown", although he later claimed he was not referring specifically to the Chelsea manager.
Conte responded by saying Mourinho was "senile" and "a little man" for making references to the Italian's ban in Italy over alleged match-fixing, which he was later exonerated in 2016.
"I think there is competition but at the same time don't forget you are talking about two young players and for Morata this is the first full season for him, and he is learning a lot from this experience. Or you can expect contempt, silence", Mourinho was quoted by the Guardian.
"Then he insults me for a second time, but now I change and now contempt [is there]".
Mourinho started this merry-go-round of superbly personal, nasty nonsense and now he is ending it - not in a blaze of further insults or an explosion of anger, but instead in a far more piercing way. "Football now is very hard to stay for many years for one club, especially in England now".
On Friday, Mourinho said he wanted an end to the story despite still harbouring ill-feeling towards Conte, who appears content to close the chapter.
"He is working very hard and I think that maybe the next game against Norwich, he could be available, in contention", Conte has told reporters, per Goal.
Mourinho was speaking after returning from a five-day trip to Dubai with the squad ahead of Monday night's Premier League clash with Stoke City at Old Trafford. "I have another year of contract with this club but, as you know very well in football, everything is possible".
Antonio Conte has been in a feisty mood lately - or maybe it's just his constantly improving English? - ready to fight anyone and everyone foolish enough to cross his path.
"What we believe really is there are some players in football world if you have the chance to sign them in January, March or July, you have to try and that's it".
