Zaha helped Palace win promotion to the Premier League yesterday with an outstanding performance.
He said: "We had so many fans here to support us. I am glad I was involved in all of this today. It is all I wanted. I have been at the club for 10 years, I have nothing but love for the club.
"Going to Manchester United is good for me, but I had to stay at Palace and get the job done.
"I was too nervous at first, but after that I thought it was just a game. I played how I know."
