They might be 3-8-1 as Major League Soccer nears the end of its two-week hiatus for the World Cup, but one feels like D.C. United’s best soccer is still ahead of them. The club welcomed the El Salvador national team to RFK Stadium on Saturday night for a friendly which benefitted the Spanish Catholic Center Langley Park medical clinic and United for D.C. The Black-and-Red looked decent too, winning 1-0 on Adam Christman’s 51st minute goal and stretching their unbeaten run in all competitions to six games in front of what was a largely pro-Salvadoran crowd.
