Manchester United boss Erik ten Hag is using drones to help with training.

Such is Ten Hag's minute attention to detail he has upgraded the DRONE that his coaches use to monitor training.

Ten Hag has only been in charge for seven months but he said: “When you change things in an organisation and change the way of playing, it's difficult.

“In top-level football, opponents want to kill you — and that has happened.

“We had to quickly adapt and our squad has been really terrific."

Ten Hag was faced with an enormous task when he replaced interim boss Ralf Rangnick in May.

That is why his team of coaches and performance analysts have also had long discussions with counterparts from some of the cycling teams who took part in last year's Tour de France over diet and sleep patterns.

And that is why, as witnessed during a training session in the recent break to southern Spain, there are now over 20 coaches and assistants overseeing the work being done.

Every session is filmed to be broken down and then presented back to Ten Hag.

He has also introduced a Dutch firm called the Talent Academy Group, made up of life coaches and psychologists who work twice a week with the players.

One of them, Rainier Koers, stood alone and watched the action as the squad prepared for the season's return near Jerez.

Of his expertise as a life coach, he stated: “Helping people is something which makes me very happy.

“I do that by listening, watching and feeling what is going on with the other person — and making them aware of unconscious behaviours."
