The Sounders are on-pace to draw between 44,000 and 45,000 fans to Thursday's second-leg of their Western Conference final against Houston, a game that gives them the best chance they've ever had to clinch an MLS playoff championship of any kind at home
Never before have the Sounders been this close to clinching any type of Major League Soccer championship on their home soil.
Last year, they had to travel to Colorado to decide the Western Conference title and then on to Toronto, where they won their first MLS Cup. In two prior conference finals decisive matches at CenturyLink Field in 2014 and 2012, the Sounders trailed on aggregate heading in to both games.
