D.C. United has acquired Dwayne De Rosario from the New York Red Bulls for midfielder Dax McCarty, a blockbuster trade that drastically alters United’s attack heading into the second half of the MLS season.

“Dwayne is a proven champion in our league and will add significant firepower to our attack,” General Manager Dave Kasper said.

De Rosario, a Canadian national team midfielder-forward, is a five-time MLS all-star and five-time all-league Best XI selection. He has won four MLS Cup titles and twice was named MVP of the championship game.

“Today we signed one of the best players MLS has ever seen,” Coach Ben Olsen said. “In order to gain a quality piece we gave up a quality player in Dax McCarty, but we feel that De Rosario is a game-changer that will help us in our push for playoffs.”
