Mats Wilander commented on what has been the biggest improvement made by Novak Djokovic in his career. The Swede said: "At the beginning of Djokovic's career, I saw there was a weakness on his body language and sometimes it was not good.
It's not good for a player to show his opponent or the world that he does not enjoy himself. You need to play some poker. It's nice to show good emotions, but it's not good when you show bad emotions. In the beginning, he was not that good and then he learned.
He improved and that may be the biggest improvement he has ever made. Novak progressed in terms of body language, positive attitude and mentality. In the big matches, Novak shows all his qualities, a great attitude and positive emotions.
His opponent is on roller coasters all the time. With Federer you never know if he is shocked or excited, with Nadal you know he is excited, but he sometimes is influenced by bad feelings. With Novak you never know what's happening, the way he behaves during big matches is the best."
On the future of tennis after that, the biggest stars retire, Wilander concluded: "Tennis means much more than Roger Federer, Serena Williams or Novak Djokovic. There is no way tennis gets less popular because of a player."
On his next match against Djokovic, Jan-Lennard Struff said: "If I serve well and I play aggressive, then I can make him struggle. Any match against one of the top players helps. You can take a lot from that and learn."
