Ross Barkley struck deep into stoppage time as Chelsea forced Manchester United to a 2-2 draw at Stamford Bridge to preserve their unbeaten run this season.
Melee broke out at the end of a relentless game in west London as United manager Jose Mourinho had to be restrained when one of Chelsea boss Maurizio Sarri’s backroom staff ran in front of the Portuguese to celebrate as the hosts salvaged their unbeaten start under the Italian.
With tempers flared at a charged Stamford Bridge, Mourinho then gestured with three fingers towards the Chelsea fans in reference to the three Premier League titles he won for the club in two spells in charge.
The visitors remain seven points adrift of Chelsea, and could fall nine points behind Manchester City and Liverpool should they win their respective fixtures later Saturday.
Anthony Martial, who got the equaliser in the comeback win over Newcastle United last time out, scored twice in 18 second-half minutes after Antonio Rudiger headed Chelsea into an early lead.
The Frenchman was greeted with a bear hug from Mourinho when he was replaced six minutes from time.
Chelsea, easy on the eye for most parts, paid for a lack of killer instinct despite dominating possession for the opening period of the game.
They were however salvaged when Barkley pounced in the 96th minute after De Gea had produced a miraculous save from Rudiger before carnage broke loose on the touchline as referee Mike Dean brought the rip-roaring clash to a finish.
