Lleyton Hewitt says that given Novak Djokovic's undefeated fall run, he finds it a little strange that the Serbian hired six-time Grand Slam champion Boris Becker to coach him. Djokovic’s long time coach, Marian Vajda, will not travel to Melbourne. Djokovic won his fourth Australian Open title last January.

“That one is probably the biggest surprise, I would say, out of any of them,” Hewitt said of the hiring. “I would have thought even if Becker was there and he was going to help out in ways, you know, Marian has obviously done a pretty good job and the success rate at Melbourne Park is pretty good. Obviously, Novak knows his game pretty well.  He just wants that little bit of outside influence and he thinks Boris can do it.”
