Anderson joined United for £17million from Porto.
Fergie said: “He’ll take time. He’s 19 and is a player with great skill. I’m sure he’ll be OK.
“I thought he found it difficult against Sunderland because of the speed of the game and the way they set their stall out made it difficult for us.
“Also if you look at the four that played – Anderson, Chris Eagles, Carlos Tevez and Nani – they’ve never played with each other.
“But we were pleased to get 45 minutes behind Anderson. Hopefully, the two weeks before the Everton game will give him a chance to improve.”
