Wow! Check out the seating map at the Messi and Friends Soccer event, scheduled for July 6th,.  As of yesterday I think there were about 22 sections completely sold out.  Look at the upper seats on the visitors side of the field this morning, only 1 section left with available seats.  Once the seating map displays, make sure you put your cursor on the USE THE MAP block and click it so you can see all the seats.
