Hernan Crespo scored the winner as Chelsea beat DC United in the second match of their pre-season tour of the USA in Washington.
There was a hint of offside about Crespo's goal
The home side capitalised on an error from Didier Drogba as Bobby Boswell headed them into a 31st-minute lead.
Chelsea hit back when Damien Duff converted Shaun Wright-Phillips' cross.
Crespo had the last word by firing home in the 56th minute, and Wayne Bridge gave Chelsea a major boost with his first appearance for five months.
The England left-back, who started the game, had not played since he was carried off on a stretcher during February's FA Cup fifth-round defeat at Newcastle with a broken ankle.
Chelsea boss Jose Mourinho named Joe Cole, Duff and Wright-Phillips in an attack-minded starting line-up.
But DC United struck first when Drogba failed to match Boswell's run and the defender headed home Christian Gomez' corner from the right.
Chelsea responded four minutes later when Wright-Phillips sent over a deep cross from the right and Duff sent a left-foot volley across DC United goalkeeper Nick Rimando and into the net.
An Arjen Robben run lead to Chelsea's winner, although Crespo looked to be in an offside position as he ran on to the Dutchman's pass and shot past substitute keeper Troy Perkins.
Frank Lampard was close to adding a third for Chelsea in the 82nd minute, having been teed up by Eidur Gudjohnsen, but he shot wide of the left post.
Chelsea, who beat Champions League finalists AC Milan 1-0 in the first match of their tour, will play the Italian side again on Sunday.
