Watch: Cristiano Ronaldo given red card, leaves pitch in tears

Portuguese star Cristiano Ronaldo is set to miss a reunion with Manchester United after being sent off on his Champions League debut for Juventus.

Ronaldo was handed a red card in the 29th minute of Juve's match at Valencia on Wednesday after tangling with Jeison Murillo. The footballer left the pitch in tears.

In one of the videos being viral on social media, Ronaldo appeared to put his hand on the Valencia defender's head and referee Felix Brych showed Ronaldo a straight red card after discussing with his assistant behind the goal.

Ronaldo looked baffled andimmediately broke into tears, throwing tantrums on the pitch.

The 33-year-old joined Juventus from Real Madrid in the summer and scored his first two goals for Juventus this past weekend in a 2-1 win over Sassuolo in Serie A.

He is the Champions League all-time leading scorer with 120 goals.
