Coach Severin Luthi thinks even Roger Federer doesn't know for how long he will play tennis professionally. Federer, 38, still competes at a high level and he has proven capable of reaching the Grand Slam finals and winning the biggest titles despite being near his forties.
On Monday, the Swiss made a winning start to his Australian Open campaign as he saw off American Steve Johnson 6-3 6-2 6-2. "I don't know for how long Roger will play, I simply don't know, I think he doesn't know either and this is good.
I believe that he is not one of those guys who will announce his retirement much in advance," Luthi told Rene Stauffer of Tages-Anzeiger. Also, coach Luthi spoke about how the members of Team Federer like to joke around so it's not always serious and things tennis-related.
"We like to have fun within the team, I think it is important that one also keeps his childish side, in tennis we travel a lot together, and if the atmosphere is right, everything is easier," Luthi said.
