Cristiano Ronaldo suffered the first Champions League red card of his career for Juventus but which games will he be suspended for?

Could he miss a return to Old Trafford?

The Portugal forward appeared to pull Valencia defender Jeison Murillo’s hair - and was shown a straight red card - although Juventus went on to win 2-0 without him on Wednesday.

Uefa has opened disciplinary proceedings against Ronaldo and European football’s governing body will deal with the case on 27 September.

Unlike the Premier League’s automatic three-game ban for violent conduct, Uefa’s punishments are on a case-by-case basis.

A one-game ban is automatic - with no right of appeal - but Uefa regulation 50.01 for the competition says that “in case of serious offences, the Uefa control, ethics and disciplinary body is entitled to augment this punishment”.

Ronaldo, 33, will definitely miss their next Champions League game against Young Boys on 2 October - but a two-game ban would rule him out of the trip to his former side Manchester United on 23 October.
