Manchester United boss David Moyes was delighted with Adnan Januzaj's performance in victory over Swansea City.
Januzaj was outstanding and the 18-year-old provided the cross from which Valencia eventually scored after Shinji Kagawa's header had been saved.
And he was also involved in the move that ended with Welbeck flicking in his sixth goal in nine games.
"Adnan has been like that since day one," said Moyes.
"I speak to him a lot and he tells me he can play anywhere.
"He is not a nervous boy. He needs teaching and understanding because he is still learning the game but his natural talent and ability is up there with the best. In time he will prove that."
