Robin van Persie will not need knee surgery and will fight to keep his spot in the Manchester United XI.
"I am impressed that people have the imagination to invent something like that," said van Persie in regards to rumors of his injury.
"I do not know where it comes from and can say with my hand on my heart that I won't be in a hospital to have the operation."
Radamel Falcao's arrival has prompted questions whether he, Van Persie and Wayne Rooney can all fit into the same side or one of them will be dropped.
But Van Persie said of Falcao, "I welcome his arrival, he makes us better. At a top club you should always go for the best, which also fits my philosophy.
"Falcao must fight for his place, as I also have to. We must duke with Wayne Rooney and James Wilson to see who's playing."
