All is not well in the camp of World number one Andy Murray ahead of the French Open which begins on Sunday.

According to British media reports, the tennis star is battling to recover from illness before the French Open serves off at Ronald Garros.

Murray has had numerous setbacks in 2017, with the 30-year-old diagnosed with shingles in February before sustaining a elbow injury in March that ruled him out of the Miami Open and Great Britain's Davis Cup tie.

Despite the challenges, top-seeded Murray trained on Thursday, ahead of the main draw for the French Open later on Friday, and is also set to attend a pre-tournament press conference after the draw.
