Cristiano Ronaldo has branded the refereeing in Real Madrid's Champions League meeting with Dinamo Zagreb as "shameful".
Real emerged as 1-0 victors over Dinamo Zagreb thanks to Angel Di Maria's 53rd-minute strike, but Ronaldo was left unhappy with the officiating by referee Svein Moen after feeling he was poorly protected, in particular after sustaining an ankle injury that required stitches following a challenge by Jerko Leko.
Ronaldo said: "I hope we will not have a repeat of this refereeing performance, it was shameful. Some referees allow them to give me stick like (the Dinamo players) did today. Referees always say before games they will protect players with more skill but few do. I do not understand it."
The former Manchester United winger went on to highlight jealousy as the reason why he feels he is often singled out by opposition players.
He said "I think it's because I'm rich, handsome and a great player. They envy me - there's no other explanation. We are very happy with the three points we took, but I'm not so satisfied with the refereeing. I hope we never have this referee again."
Real wing-back Marcelo was sent off at the Maksimir Stadium after receiving a second yellow card for diving, and, like Ronaldo, the club's assistant manager Aitor Karanka was unconvinced by the refereeing.
He said: "It's worrying to see Marcelo was sent off when Cristiano Ronaldo is receiving stitches in the dressing room. All players should be equally protected."
