Busy day on the Washington soccer scene …

*D.C. United is in Philadelphia to play the Union at Chester’s PPL Park (8 p.m. ET, NBC Sports Network). With a third match in eight days, lineup changes are certain. Bill Hamid is slated to start for the first time since returning from U.S. national team duty. Luis Silva was recovering from a blow to the head and seems unlikely to play. I also expect Nick DeLeon to sit out. (I spotted him in D.C. after the team had departed for Philly.)

*U.S. national team leader Michael Bradley returns to a familiar venue, RFK Stadium, this time with Roma, which faces Chelsea in an 8 p.m. friendly (ESPN Deportes, ESPN3.com). My feature about an American in Italy made the front of the Sports print edition:

Last night, dozens of blue-clad Chelsea supporters gathered outside the team hotel, Mandarin Oriental, hoping for a glimpse of the star-splashed Premier League squad. A handful of Roma fans found the Serie A side’s mid-day training session at the RFK practice grounds. After the match, Roma will head directly to the airport for a charter flight home. Tonight’s crowd at RFK? I am guessing 25,000.

*At Maryland SoccerPlex, the two-win Washington Spirit seeks a two-game winning streak when it welcomes Hope Solo and the Seattle Reign (7 p.m., Fox Soccer). More than 4,000 tickets had been sold by Friday afternoon.

*The MLS players’ union has updated the players’ salaries list. Not all new contracts were finalized in time for this version, but three notable U.S. national team veterans who rejoined the league were included:

Seattle Sounders MF-F Clint Dempsey: $4.913 million base salary, $5.038 million guaranteed compensation. Highest-paid player in MLS.

San Jose Earthquakes D Clarence Goodson: $315,000, $342,000

Chivas USA D Carlos Bocanegra: $228,000, $261,000
