Lendl opens up on Murray split

Ivan Lendl has opened up about splitting with Andy Murray, citing extra family commitments and the difficulty of matching the emotional high of the Briton's Grand Slam breakthroughs as factors in his decision.

The 54-year-old, who coached Murray to the 2012 US Open and 2013 Wimbledon crowns after he had lost all four of his previous Grand Slam finals, ended one of tennis' most effective partnerships over dinner in March.

Beyond a terse statement in which he talked of working on some of his "own projects" and playing on the champions tour, Lendl had steadfastly declined to elaborate on the break-up.
