London: Much of the confusion surrounding Andy Murray’s ground-breaking coaching deal with Amelie Mauresmo was resolved on Wednesday, after Murray posted some intriguing photographs on his Facebook page. The shots showed Murray working with his team in Miami, where he is in the middle of his intense summer training block.

In the foreground, you can see Murray’s physio Mark Bender working on his serving shoulder, while the background shows Mauresmo tapping away on her smartphone. This was the first indication that Mauresmo’s grass-court “trial period” has been judged successful enough for the arrangement to continue into the major tournaments of the autumn and winter, notably the US Open and ATP World Tour Finals. Although Murray, who stands only at No 8 in the list of 2014’s highest points winners, is still some way from booking his place at the O2.

Sources close to Murray indicated last night that an extended deal would be announced in the next few days. Admittedly, that is the message we have been hearing since Murray went out of Wimbledon three weeks ago. But the fact that Mauresmo has travelled to Miami, breaking her habit of holidaying in Biarritz in late July, suggests that she is committed to the project over the longer term.

Also in the photographs are the other key members of Murray’s team, assistant coach Dani Vallverdu and fitness trainer Jez Green. Both men were understood to have been hugely frustrated to be left out of the loop in the original negotiations, only finding out about Mauresmo’s appointment when the news was released to the world a couple of hours before the French Open final.

Locker-room insiders spoke of an “unhappy camp” during Wimbledon. Some even speculated that Vallverdu and Green, loyal allies of Murray’s for many years, might walk out on him. But after a little bridge-building, the whole team played five-a-side football on the morning of the Wimbledon final, and the worst of the tension now seems to have been resolved.

Mauresmo’s contribution to Murray’s Wimbledon campaign should not be overstated, for there is a limited amount any coach can do in the 10 days before a grand slam tournament. Murray’s performances were hard to categorise in any case, as they veered from magnificent — in the four rounds he played without dropping a set — to disastrous in the quarter-final against Grigor Dimitrov. A controversy boiled up in that last match, as Murray fired a few X-rated salvos in the direction of his player’s box.

Murray has always been prone to blurt out mysterious comments when struggling in matches. It is only at Wimbledon, where everyone watches him so intently, that he usually makes an extra effort to stay calm. This year, in the absence of his father-figure coach Ivan Lendl, the dam burst. Mauresmo was never going to be another Lendl, nor does she aspire to be. Yet Mauresmo is a Wimbledon winner in her own right, a woman with experience, insight and tact. And now, for the first time, she will have a real chance to guide Murray’s progress, for this Miami training block represents an opportunity to put in some technical work together.

Even Lendl, it should be remembered, had been in his position for six months before great things started to happen.
