Portuguese striker, Cristiano Ronaldo flicked his boot at Jeison Murillo as they clashed together in the 29th minute and the defender fell to the floor.
The 33-year-old left the pitch in tears as he received a red card following an off-the-ball clash with an opponent during Juventus and Valencia clash on Wednesday night.
The Portugal forward then appeared to pull Murillo’s hair in an attempt to lift him off the ground and the Valencia players immediately protested to the fifth official behind the goal.
After Referee Felix Brych consulted with his colleague, he gave Ronaldo a red card, leaving the footballer in tears as he made his way down the tunnel.
It was Ronaldo’s first red card in 154 Champions League games, 11th red card of his career and the decision means he could miss a return to Old Trafford when Juventus plays Manchester United next month if gets at least a two-match ban.
Ronaldo looked baffled and kept professing his innocence and was clearly distraught as he left the pitch in tears, still shaking his head.
“He was upset and he needs time to calm down,” Allegri said. “He needs to rise above it and focus on Sunday, even if these things leave a bitter taste in the mouth.”
Even Valencia coach Marcelino Garcia attempted to comfort Ronaldo as he walked off the pitch.
“I didn’t see the contact, I was affected by his tears. He was saying he didn’t do anything,” Marcelino said. “I spoke with him but I won’t say what I told him.”
Juventus coach Massimiliano Allegri insisted it shouldn’t have been a red card, and lamented the fact that video technology has yet to be introduced into the Champions League, as it has been in Serie A. VAR was also used at the World Cup in Russia this year.
“I’ll only say that in this sort of occasion VAR would help,” Allegri said. “It’s disappointing because now we’ll lose him for a few games and instead if there had been VAR it would have been seen that it wasn’t a sending-off offense.”
Ronaldo was dismissed in the 29th minute after tangling with Jeison Murillo. After Murillo went down inside the area, the Portugal forward gestured for his opponent to get up, then put his hand on the Valencia defender’s head and appeared to tug his hair. Referee Felix Brych showed Ronaldo a straight red card after discussing with his assistant behind the goal.
