Rooney currently has one year left on his contract at Everton, but the Premier League side will not stand in the way of Rooney moving to Major League Soccer.
Manchester United and England’s record goalscorer agreed a deal in principle last month but he cannot sign for DC United until the US mid-season transfer window opens on 10 July.
Provided there are no unexpected developments, Rooney will make his debut on 14 July, the day before the World Cup final, when DC United open their new 20,000-capacity Audi Field stadium against Vancouver.
Fitness and staying clear of injuries will have to be concern for Rooney and D.C. United. The MLS side almost averages two game a week from the Vancouver game in mid-July to the international break in September. Rooney has not played a competitive match in almost two months and it will be interesting to see his fitness levels.
Rooney will leave the Premier League as its second highest goalscorer with 208 goals, bettered only by Alan Shearer (260).
