Robin van Persie has insisted that he has no regrets about choosing to sign for Manchester United over their bitter rivals.
Manchester City are believed to have made an offer to Arsenal for the Dutch striker but he decided to move to Old Trafford.
Van Persie believes that United have provided the right environment for him to succeed and win trophies this season.
He told MUTV: "I'm very happy with my decision. I'm coming with a big smile to work every day. It's not even work, it's my hobby. I love it, I love football.
"Everyone has been so nice to me. I'm having the time of my life here so I don't regret that.
"I know how it is, obviously. In the past I had the North London derby against Spurs and other derbies in London, but this is two Manchester teams in one city, one is called United and the other is called City and that's it. They are the only teams, so it is the only derby, and the biggest derby."
Sir Alex Ferguson's side are three points clear of City at the top of the Premier League ahead of Sunday's clash at the Etihad.
