In an interview to Eurosport, the seven-time Grand Slam winner Boris Becker commented on how coaching a player is complicated. The three-time Wimbledon champion worked with Novak Djokovic from 2014 to 2016 and helped win six Grand Slam titles.
Becker explained how he convinced Djokovic to push on Nadal's best shot, the forehand: 'Coaching is complicated, it has so many facets and layers - physical, mental - which parts is more important? It's debatable,' said Becker.
'When you coach an 18-year-old is different than a 25 or 31-year-old. A good player usually doesn't listen because he is very stubborn, he is very convinced of his own quality and you can't get this away but if you give him the arguments and with the signs of today, with the technology, we can prove the player is wrong.
Djokovic did not really believe that with his style, in his backhand to break down at Nadal's game you got to go by at the forehand, most of the players would go that suicidal but because of the quality of the backhand cross of Djokovic, he was able to open up the code to get to the backhand.
It depends a little bit on the player and that's very complicated, every player has a different quality and you want to bring the best quality out of the player that sometimes it's mental, physical and tactical.'
Djokovic leads the head-to-head against Nadal, 28-25, and won their last match in last months's Australian Open final prevailing in straight sets. ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
