Seattle Sounders will host Chicago Fire in the 2011 Lamar Hunt US Open Cup final in October and there is already huge demand for tickets.

Recent reports suggest that more than 27,000 tickets have been sold for the October 4 cup final at Seattle's CenturyLink Field.

The Sounders have played in the last two finals and drew a record crowd of 31,311 in 2010 as they defeated Columbus Crew 2-1 and it looks as though they are well on the way to breaking that record this year.
