Any visitors to Los Angeles will expect to bump into celebrities, though one would think it would more likely be a movie star than a racing driver.
However that is who the Manchester United players met during their training camp in Los Angeles on Tuesday.
Reigning F1 champion Nico Rosberg visited the squad, and was presented with a shirt featuring his name on the back.
Rosberg, who retired from F1 last season after winning his maiden world title, seemed just as pleased to have met the players, making sure he got a selfie.
