The Manchester City boss was left looking embarrassed as Sarri headed straight down the tunnel
Maurizio Sarri has admitted he did not see Pep Guardiola at full-time on Sunday at the Etihad.
But Guardiola seemed upset that his opposite number had not shaken his hand before presumably preparing to tear into his troops.
Assistant boss Gianfranco Zola consoled the Spaniard as the Chelsea players went over to apologise to the travelling fans.
And Sarri has admitted he was desperate to return to the dressing room as soon as possible.
“I didn’t see at that moment,” the Italian said. “But of course as usually I will go to say hello to him later, as usual.
“It was by chance because I wanted to go to the dressing room at that moment, and I didn’t see him.
“I don’t have a problem with Pep.”
Chelsea have now lost seven of their last 21 games in all competitions and the former Napoli coach admitted he is in a precarious position.
“My job is always at risk,” he said on Sky Italia as his team fell to their worst defeat in 28 years.

“If the president [Roman Abramovich] calls, I’ll be happy, seeing as I never hear from him. To be honest, I don’t know what to expect.”
Sarri added: “I’m surprised because at the beginning of the season we played better away than at home so I don’t know what has happened but at the moment we are in trouble.
“In the last three or four matches we were without a reaction from the first difficulty so we need to understand.
“It is difficult to describe our performance, it’s difficult also to understand. We started well but after four minutes we conceded a goal in a stupid way.”
