DC United coach Wayne Rooney was back at Manchester United this week.
Ex-Norway international Jan Age Fjortoft claimed on Twitter that he had seen Rooney on a visit to Carrington.
DC United boss Rooney is back in the UK after his team finished rock bottom of the MLS Eastern Conference and failed to qualify for the play-offs.
He was seen in Cheshire last week after jetting home to see wife Coleen and their four sons.
And he reported to have paid a visit to his former stomping ground.
