Novak Djokovic can come back even better - Andre Agassi

Novak Djokovic could return to the top of men's tennis without Andre Agassi, according to the Serbian's coach. Agassi hopes to prompt a shift in the 12-time major winner's mentality as he prepares to reassert himself on the ATP Tour in 2017, but the American does not believe he is integral to that aim coming to fruition. After completing a career Grand Slam at the 2016 French Open, Djokovic suffered a severe dip in form and split with Boris Becker last December, having lost his place at the top of the rankings to Andy Murray.
