Former United States head coach Bruce Arena has tipped Wayne Rooney to make a huge impact at DC United.

The 66-year-old, who has also managed DC, New York Red Bulls and Los Angeles Galaxy, believes that the ex-Everton and Manchester United striker's arrival in the American capital is a significant coup for Major League Soccer.

"He's going to bring people in stadiums throughout the league, so I think Rooney will do great in Major League Soccer," Arena told Omnisport.

"He's a proven goalscorer throughout his career, he can come off the frontline and be a playmaker a little bit, he's got a great work ethic, he's a strong personality and that kind of presence can elevate DC United."

Rooney, who has signed a three-and-a-half-year contract with DC, will be added to the club's roster when the international transfer window opens on July 10.
