Chicago is fourth in the East with 29 points and has a plus-9 goal differential while Portland is 10th in the West with 24 points and is even on differential. It's Portland's first visit to the Windy City in eight years and marks the MLS debut of new Portland head coach Martí Cifuentes. Second-leading scorer and top assister Kristoffer Velde (4G, 6A) is in doubt after leaving a Leagues Cup this week injured. The Timbers are 2-6-1 in road games. Led by new addition and European superstar Robert Lewandowski (2G in three games), Chicago is on a four-game winning streak in all competitions.
