Arsenal ace Robin van Persie says his injury-free run is down to computers.

Arsene Wenger is one of an increasing number of manager who uses GPSports, a system which gives detailed analysis of a players contribution and work-rate during a game.

Van Persie told The Sun: "I can play three matches every week and last year I did that many times.

"But sometimes, I have to take a step back as I did against Olympique Marseille in November.

"In the phase before that, I'd played a lot and from the measurement results it showed that I had to rest.

"The trainer wanted me to start the match but at the last moment decided to go along with the results of the GPS system and that was that I could play for a half hour.

"And a couple of days later against West Brom I benefited from that."
