VIDEO: Barcelona fans troll Ronaldo with rude chant about his birthday

 This is just plain mean.

We wouldn't be able to advise Ronaldo on too many things but we think we're fairly safe in suggesting he tones down his birthday celebrations next year. The Real Madrid man has got nothing but grief for his antics last week to celebrate his 30th. He held a very swanky private party at which he was filmed singing and looking like a total eejet in a gold hat. That would be fine if it hadn't come just hours after a 4-0 thumping by Madrid's city rivals Atletico. Well Barcelona decided to stick another knife into the World Player of the year last night with their new chant. During the win over Levante on Sunday night supporters at Camp Nou sang-‘Cristiano es un borracho’ / ‘Cristiano is a drunk. Not very nice at all. https://www.youtube.com/watch?v=1S3qtdi4mgw H/T to 101greatgoals
