AC has won 14 European cups and 4 world championships (this
is a world record). It has also won 29 trophies in Italy itself.


Within Spain, Real Madrid have won 32 La Liga trophies,
which is a record for domestic wins, and have won 9 UEFA cups.


However, there are so many trophies both domestic and
international that it is hard to find a definitive list of winners, and if you
go on the forums you will see people arguing about this a lot. The most
complete list I can find is this one from late 2010, which estimates Real Madrid as the top club in history with a total of 72 trophies and puts AC Milan much lower. But for a really accurate list you would need to go through every match ever won by each side and put them all together.
