Manchester United are targeting referee Steve Bennett.
The video will be sent to the FA and Premier League and United could even request that Bennett, who took charge of their match against Birmingham at St Andrew's last night, is not assigned to their games.
United manager Sir Alex Ferguson questioned Bennett's decisions on several occasions last season, culminating in his fierce criticism of his refusal to allow United a goal in the FA Cup Final against Chelsea.
This season Bennett sent off Cristiano Ronaldo for an alleged butt on Portsmouth's Richard Hughes, who later admitted there had been no contact.
Ferguson said: "It is almost as though Cristiano is being punished for his success. There is no question there is an unfairness about it all."
It was the second time Bennett had sent Ronaldo off, having dismissed him against Manchester City in January 2006.
