To shut any milanisti who said "our achievement in the europe is more greater than juve" or merdanisti who said "we're the first one to gain treble", juve should make this uefa plaque badge on the left sleeve.
We're the first one who won all uefa major competition. And it's way much better than treble or winning more champions league (although i still want juve to win more of that cup) . I believe this can shut them up including all other fans e.g. madrid, barca, bayern, etc.
