WATCH: Ronaldo Gets Red Card In Juventus Champions League Debut

A controversial decision from the referee, advised by his assistant, sent Cristiano Ronaldo off on his Champions League debut with Juventus against Valencia.

Cristiano Ronaldo was handed a red card for shouting and what appeared as merely raffling Valencia defender Jeison Murrillo's hair in the 29th minute of Juventus' Champions League match against Valencia. Official Felix Brych consulted his assistant behind the goal before showing the Portuguese star a straight red card.

Wednesday's game was also Ronaldo's Champions League debut for Juventus and the card means he will most likely miss three matches unless the decision is overturned.

It is Ronaldo's first red card in 154 Champions league matches.

It was all too much for the Portuguese star, as he was seen in distress and in tears making his way to the dressing room.

UEFA's regulations state the following: "As a rule, a player who is sent off the field of play is suspended for the next match in a UEFA club competition (i.e. UEFA Champions League, UEFA Europa League or UEFA Super Cup). In case of serious offences, the UEFA Control, Ethics and Disciplinary Body is entitled to augment this punishment, including by extending it to other competitions."

Juventus, however, stayed resilient and defeated the Spanish team 2-0 thanks to a brace from Miralem Pjanic and a penalty stop from Wojciech Szczęsny.
