You all failed to understand what he was actually saying. I blame goaldotcom for the bad translation.
Melo was mad at the refs on Milan-Fiorentina and on Fiorentina-Lecce. He even talked how Milan and Inter are favored by the refs.
He thinks that there are double standards for Milan and Inter on one side and Fiorentina on the other side. So he says that if the refs won't be against Fiorentina as they were recently, then they can beat us. He wasn't saying that the refs are favoring Juve.
Fuck him and his disgusting team anyway.
