Former British No 1 Tim Henman has no doubt that two-time Grand Slam champion Andy Murray is on his way back to the top of the game after undergoing surgery last year.
Murray's glorious 2013, in which he won Wimbledon, ended on a sour note as he had a back operation to correct a disc problem.
Henman has been impressed with the Scotsman's return to top-level action this year - reaching the Australian Open quarter-finals and helping Great Britain to a Davis Cup victory over the USA - and expects much more to come.
"He looked in good shape," said Henman, who is expected to feature along with Murray at the BNP Paribas Tennis Classic, a pre-Wimbledon exhibition event, at Hurlingham this summer.
"Coming back after any surgery is not easy, and back surgery is quite major surgery.
"He missed a substantial amount of tennis but he played well in Australia and it was a good effort to get to the quarter-finals.
"I was also impressed how he played in the Davis Cup, in best-of-five-set matches on clay, the surface which I think caused his back the most problems.
"His attitude and professionalism is fantastic, and that is why he is having the results he is.
"He is not leaving any stone unturned and is doing everything he can in his career. I think he can go on and win many more majors.
"He is in Acapulco this week, then Indian Wells and Miami. I think this is going to be an important stretch to build momentum for the rest of year."
The Hurlingham event, which takes place the week before Wimbledon on June 17-20, will feature a number of leading ATP and WTA professionals looking to fine-tune their games, while several veterans such as Henman will add to the entertainment value.
