The Western Conference clubs clash looking to put themselves into playoff position.
They'll look to meet expectations and get in better position for a postseason spot when they meet Friday (8 p.m. ET, NBC Sports Network).
The teams were both able to get into a better run of form prior to the league's two-week break for the World Cup. LA (5-3-5) continued the hot streak when play resumed last week, beating the San Jose Earthquakes to stretch its unbeaten run to five matches. Portland (4-5-8) dropped its most recent result to Sporting Kansas City, 1-0.
