Chelsea manager Lampard rose from his seat throughout the game and that seemed to put an end to Mourinho after his side were left behind in the first half, thanks to a clinical strike from Timo Werner.
Mourinho said: “Holy shit Frank, when you lose 3-0 you don’t stand here. ”
It was a dig at Lampard after his team hung out at West Brom on Saturday before fighting to draw the Hawthorns 3-3.
Mourinho then gestured with his hands to say that Lampard was talking too much as their old friendship turned into a fierce rivalry.
There was no love lost between the duo which was incredibly close when Lampard was instrumental in Mourinho’s success in his glory days by winning titles and trophies at Stamford Bridge.
It wasn’t the only interesting moment involving Mourinho in the London derby, with the Portuguese also rushing down the tunnel after Erik Dier in the second half, when the England midfielder made his way to the toilet.
“He had to go. He had to go. Maybe it’s normal when you’re completely dehydrated, ”Mourinho said after the match.
“I knew he had to go, but I was just trying to pressure him to come back for the remaining time. “
Lampard has a history of busts on the sideline after an X-rated trade with Liverpool boss Jurgen Klopp and his coaching staff when Chelsea lost at Anfield in July.
Former England midfielder Lampard then claimed the Liverpool bench was a bit “too arrogant”.
But his final sideline with his managerial mentor showed Lampard has an advantage and is ready to face off on the sideline.
However, he was disappointed to see his team lose their lead, with Erik Lamela’s late strike resulting in the match being penalized.
And after nine perfect kicks, Mason Mount’s foul gave the home team the win.
