Former Chelsea boss Mourinho was left incensed, leapt from his seat and had to be held back by stewards after Ianni celebrated wildly in front of him when Ross Barkley grabbed a 96th-minute equaliser for the hosts.
Manchester United manager Jose Mourinho revealed he had accepted an apology from Chelsea second assistant coach Marco Ianni following the furious touchline row that erupted at the end of a dramatic 2-2 draw at Stamford Bridge.
"Maurizio saw and told that he would take care of it internally and to accept his apologies, which I did", said Mourinho.
He spent two years on the staff of Roberto Cappellacci in his native Italy - first with Cosenza and then Campobasso - before joining Sarri at Napoli, where Ianni worked as the club's technical assistant.
"Sincerely, I have not seen [what happened], but I have spoken with Jose [Mourinho], then I have spoken with a member of staff because I think we were on the wrong side, so I have dealt with it immediately", he said.
"If I speak to a member of staff and am very hard [with him] I can not come here and tell everything because then I am not credible with the staff".More news: Caravan migrants break Guatemala border fence, rush Mexico

It was something that Manchester City also displayed on numerous occasions on their way to winning last season's Premier League, so Chelsea will not underestimate the value of Ross Barkley's late, late strike.
The broadcaster once worked at Sky Sports alongside Andy Gray but was forced to leave his post for sunnier climes after being embroiled in a sexism scandal over comments he made about the Premier League match official Sian Massey, among others. "We were in the wrong on the situation".
"He is a more complete player than before but he needs to improve. I will try to focus on the performance and not on the bad result".
'I'm disappointed with the last 30 minutes.
"After we scored the second goal and third it was much easier", said Guardiola. Martial was excellent in the second half and Mourinho refused to criticise Paul Pogba for losing Rüdiger when the Chelsea defender headed in the opening goal from a corner.
