'Embarrassing from one of the greats' - Fans mock Ronaldo after he leaves pitch in tears

Cristiano Ronaldo couldn't hide his devastation after he was sent off on his Champions League debut for Juventus on Wednesday and his detractors have been quick to make the most of his misery.

The 33-year-old was dismissed during the first half of Wednesday night's Group H opener in Valencia following an off-the-ball clash with Jeison Murillo.

Ronaldo now faces a two-match ban for violent conduct, which would see him miss his side's clash at Old Trafford, but that could rise to three after UEFA determine the length of the ban in the coming days.

The Portuguese superstar, who had appeared to grab Murillo's hair, was visibly shocked by referee's decision and was inconsolable as he was led away from the field in tears.

The reaction on social media was typically huge  as fans took the chance to mock Ronaldo's misfortune.

The majority of tweets centred around the idea that the footballing great was too old to be reacting in such a manner, regardless of whether the decision was a fair one or not.

'Ronaldo crying after booting a defender and trying to rip his hair out is actually so funny,' One viewer wrote. 'Embarrassing from one of the greats'.

Another described the whole affair as 'Under-9s antics' while one joked that we now have pictures of the striker crying in every kit he's ever worn in his career.

Naturally, the incident gave many a chance to compare Ronaldo with great rival Lionel Messi, who scored a hat-trick on Tuesday night.
