Manchester United boss David Moyes was delighted with Adnan Januzaj's debut for victory over Crystal Palace.
The 18-year-old substitute unsettled the Palace defence more than any other United player and won the free-kick from which Rooney scored his first goal since March.
"I considered playing him from the start," said Moyes.
"His performance when he came on showed it would have been merited.
"He didn't looked fazed and did a lot of good things.
"He moved the ball well. He is going to be a good player."
