Didn't he high-fived Inzaghi once? I think it was when Milan played against Bologna? I wonder if there are other evidence.Watching Sweden-Portugal now, and the referee is Rosetti, the famous Milanista. I seriously hope that he never referee an Inter game again. If I'm not mistaken, Mourinho came out and said that this particular referee didn't like Zlatan. And we know from previous experience that this guy favours Milan and screws us over.
Hence why it's no coincidence that in a game where only two Interisti plays, and one only 20 mins, the only two who has been booked are our two Interisti.
