AC Milan v Celtic

Hi, I've just found out that I wasn't able to get a ticket among the Celtic supporters for next Wednesday's game but the flight and hotel are booked, so Milan here we come!

I will have my son with me and we will be wearing Celtic shirts and we will be trying to get into the game. Given all of that, where would be the best part of the stadium to try to get tickets and can I get them officially. If not is the best place to buy from a scalper outside the stadium?

I can't wait to see the San Siro. I hope it's a game to remember.
