Cristiano ronaldo sent off as 10-man Juventus ease past Valencia

In his first Champions League match with Juventus, Cristiano Ronaldo was sent off in the 29th minute for what looked like patting (maybe forcefully patting?) Valencia defender Jeison Murillo on the head, after Murillo went down in the box. I’m no Ronaldo super fan, but that has to be the most ridiculous red card I’ve ever seen.
