The Blues initially hit the front after Antonio Rudiger capitalised on their dominance in the first half before an Anthony Martial brace in the second appeared to have handed Sarri his first Premier League defeat, before Ross Barkley struck at the death to rescue a point.
He told BBC Sport: "I didn't see what happened but I have spoken to Jose Mourinho". I have made a lot of mistakes in my career, especially when I was young like him.
But he knows who Ianni is now after the Italian goaded the former Chelsea manager with an over-exuberant celebration after Ross Barkley's 96th-minute equaliser.
"At Manchester United, it's based on the fact Mourinho wants every player to do their defensive duties".
This is the reality that Mourinho must accept.
It ended with Mourinho involved in scuffles with one of Sarri's staff but both coaches sought to diffuse the row, with Mourinho saying he had accepted an apology and Sarri saying he had also admonished the staff member.
When the 55-year-old was asked about whether he was shown respect by the home supporters, Mourinho said: "No, I don't think so, but that's not my responsibility". It may fall to the club's hierarchy to make the call rather than Sarri himself. "I understood that we were in the wrong side of the situation", Sarri told BBC sport. "What I call the Chelsea "triggers", we controlled them and the reality is we conceded two goals in set pieces not organised play", he said.
"We controlled that very, very well". So let us take a look at three players Manchester United should consider signing as they look to bolster their defense in the January transfer window.
Sarri said that his side had been in control for the first hour but had then tried to pass the ball long rather than their usual style of conserving possession and building attacks.
"'We can be happy with this point because we almost lost and we are still undefeated", he said.
"I am really disappointed with the last 30 minutes". The 2-2 in last minutes is ok, ok for the confidence of my players, but I have to look at something else. I don't want the long ball, I don't want the second ball. Today I was happy with the performance for 60 minutes because for 60 minutes we played our football. 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.
