The Audi 2015 MLS Cup Playoffs Knockout Round – full of drama, controversy and golazos – is over. Up next? The Conference Semifinals, featuring the league's oldest rivalry, a Cascadia clash and a rematch from 2014.

The Eastern Conference bracket will boast a renewal of the time-honored Atlantic Cup rivalry as the top-seeded Red Bulls meet D.C. United in the semis for the second straight season. Meanwhile, Columbus Crew SC will travel to Montreal to face Didier Drogba and friends for Sunday's first leg of the other East semifinal series.

In the Western Conference, top-seeded FC Dallas visit Seattle on Sunday in Leg 1 of their series, one year after the Sounders snuck by FCD at the same stage, while the Portland Timbers host the Vancouver Whitecaps, bringing their Cascadia rivalry to the postseason stage for the first time.
