This is a method which was reportedly never used by Los Blancos under former manager Carlo Ancelotti, and represents the fresh ideas of Alonso in his major new role. He had been known to test the use of cameras installed across the training pitch during his time with Bayer Leverkusen, but the use of a drone is new to Alonso.
It remains to be seen if this method will become a regular occurrence during the Spaniard's time in Madrid - on this occasion, the drone only recorded the training session of youth players and substitutes from their Club World Cup opening game, as the rest of the squad carried out a gym session elsewhere.
