Serbian tennis great Novak Djokovic has agreed to extend his partnership with Andy Murray beyond the Australian Open. The 24-time Grand Slam champion stunned the world after announcing his great rival as his new coach in December last year.

Novak Djokovic says the partnership with Andy Murray as his coach will continue "indefinitely". Three-time major winner Murray started working with his long-time playing rival on a trial basis at January's Australian Open, where Djokovic reached the semi-finals but was was forced to retire with a leg injury.

Eurosport expert Laura Robson has said that Andy Murray continuing to coach Novak Djokovic is "really cool" for tennis in an exclusive interview.
