Manchester United coach Louis van Gaal says only skipper Wayne Rooney is a sure starter for his star-studded team.

The signings of Radamel Falcao, Di Maria, Ander Herrera, Marcos Rojo, Luke Shaw and Daley Blind have increased competition within the United squad and have enabled Van Gaal to change his formation.

United started the season with a 3-4-1-2 system, but Van Gaal played 4-4-2 during the 4-0 win over Queens Park Rangers and his long-term aim is to get the team playing 4-3-3.

Van Gaal has an envious problem in trying to fit the likes of Falcao, Di Maria, Rooney, Robin van Persie, Adnan Januzaj and Juan Mata into his starting XI.

And Van Gaal says that only Rooney knows his name will be on the team-sheet when they face Leicester City tomorrow.

"Only the captain has more privileges," Van Gaal said. "No other player has privileges.

"There are always players we put in the line-up in a team - my captain shall always play."

Van Persie is yet to score this season, and he could be the man to make way if Van Gaal wants to hand Falcao a start.

Van Gaal - who knows Van Persie well having coached him with the Netherlands squad - denies that having both players in his squad causes problems, though.

"I don't think that Falcao interfered with Van Persie or Van Persie interfered with Falcao," the former Holland coach said.

"I think Falcao is a very good striker. I also said when he was coming into his first press conference that I like Van Persie also."

"Then we have Rooney and Januzaj and we have (James) Wilson. We have five players for the two striker positions and I have to choose."
