Manchester United striker Robin van Persie believes that he is in the best shape of his life, which has helped him enjoy a tremendous run of form.
The Dutchman has netted 22 games in 28 appearances for the Red Devils since joining the club from Arsenal in the summer.
Van Persie says that he has been hard at work in the gym, and feels that the extra muscle has powered him past defenders.
"I am on a streak of matches and goals that has never happened to me before and it is all down to my fitness," he told reporters.
"My body weight used to always be around 77 kilos. Now I weigh 81 kilos. That is a difference of more than eight pounds - and it is all pure muscle.
"I haven't been spending more time in the gym lifting weights. I have got myself super-fit and as a result I am both heavier and stronger.
"It means I am stronger in battles with defenders, but I also feel like I am in the best condition of my life.
"I also recover faster. The week before last, I played on Wednesday and Saturday.
"There was only two-and-a-half days between the games, yet I felt super-fit and had no trouble doing extra work in the final part of the game."
