Football's great sides always bring together a collection of specialists in all areas to aid their preparation.
Previously, that was only linked to ball work or physical training, but little by little it expanded into nutrition, psychology and other areas as well.
At the very top level every detail matters, and every club seeks every possible advantage.
Zinedine Zidane has clear ideas about who he wants working within the club. He wants to delegate to people he trusts in their chosen field.
In his previous spell on the bench at the Estadio Santiago Bernabeu, Zidane had Javi Garcia Coll by his side at all times.
He was one of the most trusted people around the Frenchman, and although he was removed from his role by Santiago Solari, Zidane took him back upon his return.
Now, Garcia Coll has launched a plan for players to maximise their performance.
The first step was for the players to learn about the experience of other professionals so that they can take something into their own day-to-day work.
Garcia Coll then had his own personal conversations with the players.
The coach believes that Real Madrid have a great squad who work and live together well, and that the common objective is placed above each individual's own goals, which was shown by the whole squad waiting for Casemiro and Fede Valverde to finish with anti-doping tests on Wednesday before eating dinner together past 02:00.
