The 29-year-old Dutchman was a key figure in United's title-winning campaign, finishing as the Premier League's top goalscorer with 26 strikes in 38 matches.

Van Persie – signed from Arsenal in the 2011-12 off-season for a fee of 24 million pounds – believes his improvement as a player has not halted.

He revealed he spends hours watching video footage of himself playing, and believes consistent reflection on his performances will see him get better and better as the years go on.

"When Sir Alex Ferguson told me he wanted to sign me from Arsenal last year, I said to him that I was still improving as a player," Van Persie said.

"I may be 29 now, but everything I do in training is tailored so that I can become a better footballer.

"That includes watching DVDs of myself. I started doing it when I was at Arsenal. Steve Rowley, who is the head of scouting at the club, used to make me a DVD of all my actions from every game.

"I would collect a new one every Monday morning and I could not wait to watch it because it enabled me to study both my good moments and my bad moments in every game I played. When I was younger, that kind of attention to detail was not possible.

"Now I get a full understanding of whether I made the right or wrong choices in every game. I have continued to do that at United. 

"Sometimes you think you have done okay in a game but, when you watch it again from a different angle, you realise that there were better options you could have taken. I find that kind of detail so important for my own development.

"It is not about watching my goals again. It is about identifying mistakes and the desire to improve. I want to learn all the time."
