Antonio Conte's frustration is set to increase with the Tottenham manager expected to be banned for next week's crucial Champions League match at Marseille.
The Italian was sent off by referee Danny Makkelie in the closing stages of Wednesday's 1-1 draw at home to Sporting Lisbon for his remonstrations at the decision to disallow Harry Kane's stoppage-time strike.
A red card shown to an official in a UEFA competition carries an automatic one-match suspension, but Conte will not just be merely missing from the touchline in Marseille, where Spurs need a draw to qualify for the last 16.
He will not be permitted from making contact with his players before or during the fixture at Stade Velodrome and will have to sit in the stand.
Article 69 of UEFA's disciplinary regulations states: "A team manager/coach or other team official who is sent off or suspended from carrying out his function may not be in the technical area or communicate direction with the team's players.
"In addition, a team manager/coach or any other team official who is suspended from carrying out his function may not enter the dressing room or tunnel before or during the match."
Further punishment could also come Conte's way once referee Makkelie has handed in his match report of the Group D fixture.
Kane's goal being ruled out resulted in the clash between Tottenham and Sporting finished as a 1-1 draw, which means each club in the group can still qualify for the knock-out stage.
Conte was still seething when he spoke afterwards and UEFA may also investigate his post-match comments.
During his short press conference, the 53-year-old accused VAR of being dishonest, creating "big damage" and insisted it would not have disallowed Kane's goal had it been for a "top team, in an important game".

"I think there are moments that maybe you can be a bit intelligent to understand you have just disallowed a regular goal because the goal was regular. The ball is in front of Kane," Conte insisted in his press conference before he walked out after one question.
"And then the VAR. I repeat you know I don't comment on referee decisions but the VAR, this season, I don't know why between Premier League and Champions League, we are not so lucky.
"I don't know why until now we are also the only team who repeated the penalty and every penalty I go to see, if the keeper move on line, I see a lot of the time. I want to see repetition of a penalty in Premier League.
"I think we are not so lucky with VAR but I think they create big damage. I would like to see if this type of decision you can take with a top team, in an important game, yeah I would like to see if VAR is so brave to take this decision.
"I repeat this unfair decision because the ball is in front of Kane. Sorry, but I am really upset because sometimes you can accept this situation and sometimes I think it is not good because I don't see honesty in this type of situation and when I see this I become really, really upset."
