Manchester United striker Robin van Persie says new signing Radamel Falcao has to fight to earn a regular place in Louis van Gaal's side.
The Colombia international joined the Red Devils on loan for a reported fee of £6m with an option to sign permanently for £43.5m at the end of the season.
He joins van Persie, Wayne Rooney and Angel Di Maria to form one of England's most powerful offensive departments.
"I welcome his arrival, he makes us better," the Dutchman told Fox Sports NL.
"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 is playing."
The 31-year-old also rubbishes rumours suggesting the reason the Colombian was signed was because he had to undergo knee surgery.
"I am impressed that people can pick up the imagination to invent something like that," van Persie added.
"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."
