United shocked the football world on deadline day by completing the signing of the much-vaunted Colombian on a season-long loan deal.
Louis van Gaal's side have the option to make Falcao's move from Monaco permanent, with the addition giving the United boss a mouth-watering array of attacking talent to choose from.
It raises questions as to how United will utilise the striker - a subject Rooney was not keen to talk about, preferring to focus on the impact the signing will have at Old Trafford.
"I obviously don't know how it could affect my role, that is something you'd have to ask Louis van Gaal," the England stiker said
"But I think is a fantastic signing, he is one of the best players in the world.
"It is a real sign of intent from Manchester United and an exciting signing for us."
