Andy Murray admits he is no closer to appointing a new coach ahead of his return to ATP World Tour action next month.
The world number four had hoped to find a successor to Miles Maclagan, who he sacked in July after two and a half years together, before the China Open in Beijing, which begins on October 4.
Murray told BBC Sport: “(The situation is) the same as it was before the US Open. I’m still looking into it and trying to find the best person that can help me.
“I’m going to have to be patient with it, take my time a little bit and I’m sure I’ll find someone that will help me.
“I haven’t spoken to anybody yet but I’ve spoken to the guys that I work with and I’ve spoken to my mum about the people that I might like to work with.
“I’ve got to try and find out the availability, how many weeks people are willing to do and make the decision based on all the information.”
Maclagan oversaw Murray’s rise to the top of the game after linking up with the Scot in 2007 but a difference of opinion over the direction the 23-year-old should take and the role of part-time coaching consultant Alex Corretja led to the split.
Murray began life without a full-time coach in stunning style, beating Rafael Nadal and Roger Federer to retain his Masters title in Canada, fuelling belief he could break his grand slam duck at the US Open.
But, after sailing through the first two rounds, the British number one was beaten in four sets by Stanislas Wawrinka in round three.
Murray struggled physically against the Swiss and he has vowed to address those issues as he continues his quest to win one of the sport’s major titles.
He said: “I don’t (know what happened), I’ve been in very good shape and I haven’t felt like that for a very long time and I’ll make sure it never happens again.
“It was a disappointing end to the American stretch. I obviously had a good start to it and didn’t finish particularly well. Physically I wasn’t great and that’s what I was most disappointed with.”
Murray’s troubles were in stark contrast to Rafael Nadal, who cemented his status as the best player in the world by winning a third consecutive grand slam title.
“It’s a great achievement,” said Murray, whose schedule next month also includes being best man at his brother Jamie’s wedding. “He’s one of the greatest players ever.
“I’ve got four or five months before the next slam. I need to get physically stronger, improve my game and then I’ll give myself the chance to beat him.”
