Ronaldo finished the 1-0 win needing stitches after an ugly tackle which was missed by ref Oddvar Moen.
"I do not understand. I'm sad because the referees say they will protect the most skilled players. Some players can't get close to me, so they kick me," rapped Ronaldo.
On the jeers, the former Manchester United added: "It is because I am beautiful, rich and a great player, because they are jealous. I have no other explanation."
