Prozone measures the movement and location of football players throughout a match. I've always wondered how the data were collected. Here's a description from a story on Wayne Rooney.
The ProZone figures are compiled by putting sensors around a pitch and on boots to pick up how much distance and which areas the players run into.
The figures show that 31 per cent of Rooney's game is played in the central attacking zone, 22 per cent in the centre of the pitch but also that nearly ten per cent of his game is spent defending.
But it can also pick up that Rooney's top speed is 9.7m per second which also sets him out as a super fast sprinter.
They are staggering figures which set him out as a hard-working, superfit player who covers an incredible amount of ground for the benefit of the team.
In fact, Rooney covers so much ground that Nike has developed their new boot, the Air Zoom Total 90 III, with their Everton and England striker in mind.
The article compares the distance Rooney runs in a match with other players:
On average, Rooney covers up to 1,500 metres more than his striking rivals as he can run up to 11.82km in a match which makes him one of the hardest working players in the world.
That is up to 1,200m more than Portugal superstar Luis Figo, who would be expected to cover more ground from his position on the right of midfield.
Interesting. Figo didn't do anything yesterday to suggest he likes to get around much. Rooney, by the way, was called for a foul by Swiss referee Urs "Hole" Meier when a Portugese defender stepped on his foot, breaking his metatarsal bone. It was an early sign that this fellow wasn't seeing things from the English point of view.
