Juventus coach Massimiliano Allegri felt the video assistant referee (VAR) technology could have helped in the incident that led to Cristiano Ronaldo being sent off.
VAR was used largely successfully at this summer’s World Cup but is not yet in use in the Champions League.
“Going down to 10 men in the Champions League for an incident like that is disappointing,“ Allegri said.
“We risked losing tonight with this and we’ll miss him for the next games too.”
Ronaldo will definitely miss Juve’s home match against Young Boys on October 2nd.
It would seem unlikely that his ban would be extended, with Article 15 of Uefa’s regulations stating that bans of more than one game are for offences such as abusive language towards a match official, serious assault or for receiving a caution or red card on purpose.
Two penalties from Miralem Pjanic gave Juventus the victory in Valencia.
