Danny Welbeck inside the penalty area.
That goal – United’s fourth – capped a ruthless performance by the Reds against a Wigan side that slumped to defeat by the same scoreline at Old Trafford back in September.
“It was a very good performance we scored the goals at the right time,” van Persie said. “We've played Wigan twice this year and won 4-0 both times, so that's good for goal difference.
“Everybody's helping each other and everybody wants to share the goals. Look at the last goal – Danny wanted to give the ball to me so I could score. Everybody's like that. I'm like that, Chicha is like that... everybody wants to share the goals and that, in my opinion, is the way to score heaps of goals.
“Hopefully we can keep it going. We’ve had a couple of games where we've had high scores but we want to score even more goals because that could be vital come the end of the season.”
