Great Britain's Andy Murray remains optimistic that he could once again return to his old form. Former world No. 1 Murray, now ranked at No. 382, returned to action from a hip surgery this past June at the Fever-Tree Championships, held at the Queen's Club.
The 31-year-old was absent for 11 months as his hip issue eventually required a surgery. Since his return, Murray has won a couple of thriller and long matches and proved that he can't be taken for granted. However, the three-time Grand Slam champion still isn't anywhere near the level he was during the best days of his career.
Murray's style of play -- which includes exceptional defence, lots of running and perfect court positioning -- has always demanded an exceptional physical readiness. The two-time Olympic champion believes that getting back to his old fitness level is the key to his future success.
"It has been a physical thing that's been holding me back and hampering me. Once I overcome that, I do believe that my tennis will be able to return to the level that it was at," Murray told the Wall Street Journal.
Murray made a successful return to Grand Slam action as he beat Australian James Duckworth in the US Open first round on Monday. 2012 US Open champion Murray is set to clash next against former world No. 7 Fernando Verdasco.
