Ronaldo, sent off for collecting two yellow cards in Sunday's Clásico victory at Barcelona, feels he's being persecuted and unfairly treated.
Former Premier League referee Gallagher was quoted on the BBC on Monday night: "The message they've got to send out is it's unacceptable to push a match official".
Marco Asensio scored Real's third with a stunning long-range goal in the 90th minute. "We did well in the first leg, but we have to play the whole tie until the end", Real Madrid's official website quoted Zidane as saying ahead of the match.

"Barcelona are a good side that can hurt you, I have no doubt about that".
