Tottenham were tied with a penalty kick by Newcastle United in the last minute of the third round of the Premier League. Mourinho was very dissatisfied with the result after the game.
Lucas scored for Tottenham in the first half, but Dell sent a handball in the final stage of the second half and Newcastle equalized the score with a penalty kick. After the referee blew the final whistle, the Tottenham assistant was shown a red card for dissatisfaction with the penalty.
Speaking of the assistant coach being sent off after the final whistle blows, Mourinho said: "In some clubs, even after the final whistle blows, important things may happen. However, for us, I know it will be over after the final whistle."
Mourinho was referring to the Manchester United match against Brighton last weekend. At that time, the referee originally blew the final whistle, but after looking back at VAR, the referee determined that Brighton forward Mopai had a handball foul in the penalty area. Manchester United won a penalty and Fernandez completed the lore.
