Djokovic says sharing secrets with Murray feels 'strange'

Novak Djokovic admits it has been "strange" to have Andy Murray working as his coach but the winner of 24 grand slam titles believes he will benefit from one of his greatest rivals taking a "fresh look" at his game.

Djokovic spoke also of his frustration at being "kept in the dark" over Jannik Sinner's doping case, accusing the game's authorities of double standards and a lack of transparency.

Murray, who retired after the Paris Olympics at the age of 37, made the shock decision to join Djokovic's team in November and recently spent 10 days with the Serb in preparation for the new season. Although Murray is not with Djokovic for the Brisbane International this week, the British two-time Wimbledon champion will join him in Melbourne for training before the Australian Open.
