Robin van Persie admits he couldn't be happier with his progress at Manchester United.

The Dutch striker has hit the right notes ever since he arrived at Old Trafford in the summer and has already bagged 22 goals for the Premier League leaders.

RVP says he has felt in tune with his new team-mates and surroundings ever since he made the controversial £22million switch from Arsenal.

He said: "It's gone as well as I've expected it to go.

"I go into work every day whistling - as from the first day they've made me feel welcome.

"The boys made me feel right at home. Training is really good and I see things I've not seen in a long time.

"It is a very pleasant environment to work in.

"Every day I work on new things. I have become alert to small details that make me better."
