This was the biggest game in Real Salt Lake history.
Without a doubt - by far.
Sure, other US teams had won an earlier version of the Concacaf Champions Cup, but the competition was much different - played entirely in the US, and over a short period of time. But in 2008 the Confederation restructured the competition into something much more challenging.
To date (2021) no team outside of Mexico has won the CCL, and only 4 MLS teams have made it to the final. Liga MX teams have won the competition every. single.
