Everton manager Roberto Martinez and former Arsenal striker Thierry Henry have been using drones to film their training and coaching sessions, ex-England international Michael Owen has said.
The technology is being used to offer a bird's-eye view of the players involved in a session, making for easier analysis of positioning and movement on the pitch.
Former Liverpool centre-forward Owen said in The Guardian: "It's becoming a thing in football now. At Everton's training ground, Roberto Martinez wants all his tactical sessions filmed from above -- you can really see the game from a different perspective.
"Managers always see from the side, from the sideline, the dugout -- a lot of people wonder why managers go up into the stand; it's because you can get such a better picture tactically where your men are, and how things are going. Thierry Henry [when] doing his badges -- he wants all his sessions filmed from above.
"You go one step further with a drone. A lot of teams now are using this drone technology to go up and film training sessions so you then can literally say to people you're in this position, you should be covering. It really is getting some traction in the sporting world as well.
"It's a great way of watching football, mainly tactically, to envisage where your players should be where they're going. Down at Dragon Park, where we've been doing a lot of stuff with the Welsh FA, as I say people like Thierry Henry have been using it to go and pass their pro licence."
Owen, whose M7 Aerial company offers the drones, added: "The basic ones are £3,000 to £5,000, depends on the camera. I would suggest Everton are paying by the hour."
Ex-France international Henry is currently working with Arsenal's under-18 team while undertaking his coaching badges as well as working as a TV pundit.
This week, Arsenal manager Arsene Wenger told Henry he will have to undergo a "psychological and mental transformation" if he wishes to succeed as a manager.
