Anderson joined United from Porto in the summer.
The Portuguese winger said: “Anderson is a fantastic player and it’s no surprise to anyone at United that he is playing so well.
“He is young but he has done a great job since he came to us.
“He is a man. Just because he is 19 it doesn’t mean he cannot compete with players who are older and more experienced than him.
“Anderson is a different player to Scholes and Keane but he has similar qualities to them.
“Every player has his own style, his own mentality and Anderson is showing people what great qualities he has.”
