Former world No 1 Andy Murray has arrived in Abu Dhabi for an extended stopover and took to the courts at the International Tennis Stadium at Zayed Sports City on Thursday to get in some practice. Murray, 30, a regular visitor to the capital this time of the year to take part in the annual Mubadala World Tennis Championship, where he has twice been crowned champion, is not part of the tournament's main draw. The three-time grand slam champion missed the final six months of 2017 with a hip injury and it is understood the Scot viewed Abu Dhabi as the perfect layover en route to Australia, where he is scheduled to play the Brisbane International starting January 4, to cram in some warm weather training.
