And whilst the Dutchman accepts there was an element of good fortune about his effort, the former Arsenal man recognises it was a special strike.
"It is hard," Van Persie told MUTV.
"Maybe if you look at the day, the occasion and the importance of the goal it was my best one.
"It was a great pass from Wayne (Rooney) for a start.
"He had to spot my run because I went in front of Ron Vlaar.
"It was straight into my path. I was counting my steps. The only thing I had to do was time it right and keep my body straight, level with the ball.
"You need to be a bit lucky with those goals because most of them go over or wide. That didn't, which was a big relief."
