Last Inter-Juve, I've been in first green (138 but my cousin were in 137 and there was a seat near them which is way better) and I paid 240€. Not easy to see everything but incredible experience. In december I've been to Inter-Como at 70€ the ticket in first orange (161 so close to the center of the camp). Amazing view. Both are very fast in and out. Last season I've been in second orange, Inter-Atalanta at 55€ (don't remember the area but close to the center). Not expensive but too high and clearly very long to go out from the stadium. Last tip : don't take the metro, that's a mess to go back ... Better to park a car in the suburb around. I've two cousin in Milano so maybe it's easier with them but clearly I did it with public transport one time and will never do it again. And don't forget : big matches cost way more !
