Manchester United legend Bryan Robson says Anderson can become a world star at Old Trafford.
"Ando has terrific talent and great energy levels," Robson told the Manchester Evening News.
"He is quick to get up to people to make his tackles. I just think he needs to have a little look at Paul Scholes the way he quickens the tempo of the game at certain times and then slows it down at other times.
"If Ando takes that on board he can be a top, top player for United. He has got all the ability. But sometimes he closes people down with great enthusiasm but then when he is on the ball he still plays at the same pace.
"It can be a bit 100mph. That's because he is young and people have to realise that the more he is going to play the more experience he will get and playing with great players and learning on the training ground he will master that.
"Brazilians are not normally 100 mph players. They like to slow the game down then quicken it up. Ando though has lovely technique like all the Brazilians."
Robson added: "I don't think it really went wrong for him last season. He is 22. You don't get a finished article from a player until they are 24.
"He is still learning the game in the midfield role. He has taken on board what they want from him and I can see an improvement."
