The Dutchman has hit the ground running since his £24m move to Old Trafford, netting 22 goals in 28 appearances in all competitions so far this season.
“Arsenal is a great club and I always had a really good feeling, but after eight years sometimes you feel that you need a new challenge,” said Van Persie. “I know why I went and I’m sure it’s for good reasons.
“If you look at the last couple of months, it explains it all. I’m seeing things again that I didn’t see for a long time.
“When I first came to Arsenal years ago [in 2004], I saw things from [Dennis] Bergkamp and Thierry Henry I’d never seen in my life before. Now I’m seeing those things again and that makes me really happy.
“It’s like a kid in a sweet shop. It’s like, ‘Yes, this is nice, this is good, this is having fun, this is enjoying yourself.
“All these little things added together make a big difference. It makes me feel that I’m surrounded by champions.”
