Welbeck was named man of the match.
"He [Welbeck] played really well. I think he was good in the combinations and played a big part in the build-up to the first goal, passing and moving to make space. A couple of times he got the ball when they made a mistake. I got it one or two times when they misplaced the ball," said Van Persie.
"He has been brilliant. He is still young and has been really good in training, working his socks off. He is a very positive guy who wants and loves to play football. He did really well."
