​Juventus boss Massimiliano Allegri believes that Video Assistant Referee (VAR) would have overruled the referee's decision to give Cristiano Ronaldo a red card during their 2-0 win over Valencia in the UEFA Champions League.

The 33-year-old who was making his European debut for Juventus was given a straight red after clashing with Jeison Murillo, with the incident being spotted by the assistant referee who immediately communicated the same to Felix Brych.

This was Ronaldo's first red card in his UCL career spanning 154 games, with the decision meaning that he could miss the game against ​Manchester United at Old Trafford, if slapped with a two-match ban.

"I can only say that certainly the VAR would have helped the referee in this situation because to be down to ten men in the 20th minute in the Champions League for such a situation is disappointing. We risked losing tonight and now we can only hope he is not banned for long," ​Allegri said post the game.

Fellow teammate Leonardo Bonucci too was surprised by the referee's decision to show him a red card, though he was pleased by the team's reaction post the incident.

"I think it was just a normal clash, but I was a long way off. It seemed like Murillo put his hands on him first, but it seemed like a normal clash. He was pretty angry [in the dressing room], but what can we do? Unfortunately the referee saw this -- not very well -- but the important thing is we responded as a team."
