Eladio Parames, the spokesman of Real Madrid coach Jose Mourinho, has slammed Barcelona defender Dani Alves over his appearance.
The Brazilian scored Barca's second goal during Wednesday night's Copa del Rey quarter-final victory.
"What's changed since he [Dani Alves] came to Spain. He's undergone surgery on his ears, they've become smaller. And he's wearing glasses like an intellectual. However, a donkey with small ears and glasses is not all of a sudden a doctor, he's still a donkey," Parames tweeted.
Madrid currently lead Barcelona by five points in La Liga.
