Murray rues fact he can no longer be `friends` with `old chum` Djokovic

London: British tennis star Andy Murray has admitted that he and childhood friend Novak Djokovic could not be friends anymore because there was a lot on the line when they played in big matches, and a professional friendship was the best way to go about it.

Murray and Djokovic who were born seven days apart in May 1987, first clashed as 13 year-olds in Tarbes, France, with Novak saying that it was his first international tournament and Andy had crushed him in their match. The World No. 1 added that they have known each other since they were 11 and had lots of respect for each other, whether on or off the court but now it was different because they were big rivals. Murray also said that he messaged Djokovic sometimes and they had spent a lot of time discussing various issues within tennis, hoping that it would be different when the two players finished playing tennis.
