Antonio Conte

The two managers shook hands after a 2-2 draw where tempers flared but then faced off on the pitch before being separated by players and staff from both teams.

Both managers were also shown red cards by referee Anthony Taylor as a result of the fracas.

The FA is also investigating Tuchel's comments after the German coach slammed Taylor for his decisions.

Tuchel accused Taylor and the Video Assistant Referee of making wrong decisions which ultimately helped Spurs come away from Stamford Bridge with a point.

"I am very happy to have signed a new contract with Chelsea," Conte told the club website.

"We worked extremely hard in our first year to achieve something amazing, which I am very proud of. Now we must work even harder to stay at the top."

Conte originally inked a three-year deal on his appointment last summer, after leading Italy into the European Championships.

It is understood the new contract represents improved terms for the Italian, but is not an extension.
