All three United players were on the scoresheet in the 3-2 triumph.
"You see van Persie is just a top goalscorer," Rafael told MUTV. "All the time he has a chance, he can put the ball there. What a goal. He's a top player and I'm very proud for him. (Kagawa) is a quick player. He has ability, skills, I think he has a future here in Manchester!"
