The Brazilian has shone in moments so far in preseason.
And Ancelotti, ahead of facing Chelsea in Charlotte, said: "We've got to be patient with him, he's shown great quality and talent. As with Güler last year, we don't want to put pressure on the young players.
"There's a lot of pressure behind him, he's a player who is loved all over the world, especially in Brazil, but we have to be patient with this type of player. Especially with young ones."
He continued: "The game against Chelsea should be similar to the Clásico. They're pre-season games, we have to improve the players' individual fitness. After that, we'll all come back together to prepare for the first game."
