After going a goal down to the LA Galaxy at Seattle's Qwest Field yesterday, RSL fought back to grab an equaliser through Robbie Findley before winning 5-4 in penalties to take out the title this season.
Now they are back home, the win is beginning to sink in for all the players who were treated like royalty at Salt Lake International Airport.
"This is just great," said Clint Mathis. "This is something you don't see in America for soccer at all."
"Phenomenal," said RSL coach Jason Kreis."It feels very good to finally give something back."
About 400 fans turned up at the airport to congratulate the team and get photos and autographs from their heroes and share in the glory with the newly crowned champions of Major League Soccer.
