The Seattle Sounders are one result away from making history for MLS in a tournament where clearing the final hurdle has traditionally been a problem.
After securing a 2–2 first-leg draw in Mexico City last week thanks to two Nicolas Lodeiro penalty kicks, the Sounders return home knowing that a win of any kind against UNAM Pumas in the second leg will be enough to win the Concacaf Champions League title. No MLS club has won the title in the CCL era (Real Salt Lake, Montreal Impact, Toronto FC and LAFC have reached the final and lost) and Mexican clubs have won every Concacaf title dating back to 2006.
