Rooney has reportedly agreed "in principle" to a $17 million (12.5 million pound) deal with the MLS club that would see the 32-year-old depart Everton, his boyhood club, just 12 months after rejoining them from Manchester United.
However, Everton manager Sam Allardyce said Friday that Rooney had not yet asked to leave.
'The Washington Post', citing an unnamed source close to DC United, reported that the chances of Rooney coming to the US capital are "50-50" and that no formal agreement had been reached.
