D.C. United head coach Wayne Rooney has called for changes to Major League Soccer.

The Manchester United legend, who has underwhelmed since taking charge of the worst team in MLS, is not happy with the standard of refereeing.

Rooney spoke about the officiating in the league after his side lost 2-1 to Real Salt Lake.

"There is six games tonight, so why do we get a USL referee?" Rooney said after full-time.

"The guy has refereed four games in the MLS before, I don't get it. Where are the MLS referees? Because that is not good enough.

"And they can ban me if they want, or fine me, but I am sick of it. If this league wants to grow and improve they have to do it with the officials as well.

"It is not just the referee. There is a group of people who are getting these decisions wrong and it needs to improve."
