Seattle Sounders fans bring it once again with tifo ahead of Portland Timbers playoff clash | THE SIDELINE

The Sounders-Timbers rivalry never fails to disappoint, both on the field and in the stands.

Whether you're at JELD-WEN or CenturyLink, the pregame tifo is always a sight to behold, and Sounders fans didn't disappoint ahead of their team's Western Conference Semifinal first leg against their archrivals.

That's about as clear as it gets: the Sounders will do all they can to make the game a living nightmare for the Timbers. Can the men from the Rose City cope?
