The Red Devils are currently top of the Premier League table and still remain in the Champions League and FA Cup.
"We have unbelievable players. I know the boss has two or three teams. He doesn't play eleven players all the time, he changes players and I think he has an unbelievable squad," Anderson told the club's official website.
"I don't want to be the manager at this moment because there are a lot of quality players. The boss tries to keep everyone happy. Sometimes that's difficult, but that's the club - this is Manchester United."
Anderson joined United in the summer of 2007 from Portuguese club FC Porto.
