if your hotel is on the west side of the city, closer to the stadium, then i would recommend that you take the malpensa express, which is the train...and not the malpensa shuttle, which is the bus
we took both during our trip...we took the malpensa express (train) INTO milano...and the malpensa shuttle (bus) FROM milano to the airport
we did this because the train takes you to the cadorna station in milano, and not all the way through the city to the north side where the bus drops you off at the centrale station
our first hotel was near the stadium so taking the train only to cadorna worked well. at the end of our trip we had changed to a hotel near the centrale station, so taking the bus back to the airport worked well
with your hotel being on the west side of the city (per SANT's post), traveling on the train to the cadorna station should be just fine. plus, the train is nicer, quicker and you can see more from the train than you can from the bus
once you reach the cadorna station, find out which subway station your hotel is located near and take the subway. the subway in milan is very easy to use
and i would agree with SANT...do not take a taxi to/from the airport...it would be very expensive and should not be necessary with a little planning on your part
have fun at the game...we had a blast!!
