Anderson fears Manchester United will lose their competitive edge once Sir Alex Ferguson retires.
Anderson, who joined Manchester United from Porto in 2007, says he would be interested in going back to the Portuguese club at some point in the future but has ruled out a move to Benfica. He told RTP: "I would like to return to Porto one day, but I would never play for Benfica. I'm sure of that. It's not in my plans to play for Benfica, although I respect the club."
