Jose Mourinho's latest return to Stamford Bridge was unlikely to ever pass off quietly, but we did not expect it to end with him leaping off his perch in the visiting technical area to hunt down a Chelsea staff member like he suddenly had an Eva Carneiro flashback.
"In the second half we dropped more, we let them have more possession and we made some silly mistakes so they got some counter-attacks".
He also didn't need to hit back at the Chelsea fans, but when you throw away three points you so desperately want with nearly the last kick of the game, it would be testing the resolve of anyone, never mind someone as emotional as Mourinho.
Sarri also said he would speak to Ianni again on Sunday. "We were in the wrong on the situation".
"At this point of the season one point more or one point less is the same", said the Italian.
Antonio Rudiger's first-half header had given Chelsea the lead before Anthony Martial's two goals put United in front. I spoke with my staff, and then [Ianni] agreed to speak to Mourinho and say sorry.
The angry scenes at the final whistle will understandably claim much of the attention, with Mourinho reacting to some unnecessary gloating from Ianni.
José Mourinho had kept to his word not to over-celebrate if his team were winning and, in fairness, Chelsea fans had shown no appetite to hound him in the way that had happened on his previous visits back to his old club.
But Martial, who has played in six of United's nine Premier League games in 2018-19, has dismissed talk that he does not get on with his manager. "We always tried to play, there was no time-wasting".
"After the goal to make it 1-1 we didn't play our football, only the long ball". He said: "We are not organised like this".
The former Monaco man was disappointed to concede so late but hopes their improving performances will stand them in good stead against Juventus in the Champions League on Tuesday. I don't want the long ball. In fact, since Jose Mourinho took over in 2016, no other player has contributed more goals than Martial, who has registered 23 goals and 18 assists in 96 games.
Still, it would be good for him, and United, for the story to focus on football once again. "I have seen the match on the bench, and now want to study the second half of the match". The Football Association is likely to want an explanation and, in the circumstances, it was nearly a surprise Mourinho calmed down quickly enough to shake Maurizio Sarri's hand at the final whistle shortly afterwards.
