Tuchel had previously received a one-match touchline ban and £35,000 fine for his confrontation with Spurs boss Antonio Conte at the end of the game.

The 48-year-old has until Thursday, 25 August to respond to the charge.

A statement by the FA said Tuchel's comments "questioned the integrity of the match referee".

"It is alleged that the manager's comments in his post-match press conference constitute improper conduct as contrary to FA Rule E3.1," the statement read.

"The imply bias and/or question the integrity of the match referee and/or bring the game into disrepute."

Following the draw at Stamford Bridge, video assistant referee Mike Dean admitted an error in not asking the on-field official Taylor to check his pitchside monitor after Spurs defender Cristian Romero's hair-pull on Chelsea left-back Marc Cucurella.

Play was allowed to continue instead, with Harry Kane heading a 96th-minute equaliser for Spurs seconds later.

Tuchel was allowed to stand on the sidelines during his side's 3-0 defeat by Leeds at Elland Road on Sunday after his ban was suspended temporarily, pending the full written reasons for the decision.
