Ronaldo could miss Old Trafford return

Ronaldo saw red during the first-half of the 'Old Lady's clash against Valencia at the Mestalla, after clashing with Jeison Murillo. 

There was not much in the incident, although Ronaldo did place his hand on the Colombian's head, but referee Felix Brych consulted with his official behind the goal who advised him to show a red. 

Ronaldo and the rest of the Juventus team were stunned, and he left the field in tears. 

If he recieves a full ban, he will miss a minimum of two games, possibly three. This could rule him out of both the home and away clashes against his former side. 

Ronaldo has been back to Old Trafford once, with Real Madrid, scoring as 'Los Blancos' knocked out Sir Alex Ferguson's side.
