The former Arsenal striker completed his controversial move to Old Trafford yesterday.
"I love to play with Wayne Rooney," said Van Persie. "He is world class. When I look at players, I like to see if they can adapt in every single game.
"Wayne Rooney can score a lot of goals. He can make assists. He can play for the team. He works hard.
"But it is not just him.
"(Paul) Scholes and (Ryan) Giggs are world class and have been proving it for 20 years.
"I like to think we are all in it together.
"You need every single player to achieve greatness."
