Man Utd fume over Ronaldo dive booking
"And on the Ronaldo incident, Carlos Queiroz (assistant manager) has watched the video, and it was outside the box but he was definitely caught by the Everton player.
"To get a yellow card for that was ridiculous. The referee thought he might have to give a penalty kick, so he booked Ronaldo instead, it was a bad decision."
Ferguson confirmed that defender Mikael Silvestre has been taken to hospital for a scan on the knee injury that forced him to be carried off in the second-half.
