Rivalries are the cornerstone of any good sports team. Teams are playing for more than trophies or championships. It's about honor and pride, bringing the best for the crest.
And for Real Salt Lake there may be no greater rival than Sporting Kansas City.
The long-standing rivalry picked up public wind following a heartbreaking defeat on penalties in the 2013 MLS Cup final.
But it goes back further.
Prior to the start of the 2011 season on March 8, Real Salt Lake was tied 2-2 in a preseason match in Arizona when all-out war broke out.
