Ivan Lendl has been without a coaching client since parting with Andy Murray earlier this year, and that situation looks set to continue after Tomas Berdych revealed that his attempts to recruit the Grand Slam winner had failed.
Berdych was looking to benefit from the tutorship of his countryman after seeing the positive effects that the Czechoslovakian parted onto Murray.
The duo enjoyed a hugely fruitful partnership together. The British no.1 ended a run of four Grand Slam final defeats in as many attempts after recruiting Lendl as he went on to win the US Open in 2012, Wimbledon a year later as well as an Olympic Gold medal.
They separated after Murray's difficult rehabilitation phase from back surgery and the Briton hasn't been able to enjoy the same sort of success since.
Murray, a world no.3 under Lendl, threatened to rival the likes of Rafael Nadal, Novak Djokovic and Roger Federer regularly, but things have since changed.
Grass not greener
After a lean spell without a coach, Murray, hoped for an upturn when he appointed Amelie Mauresmo before Wimbledon. However he failed in his title defence at SW19 and couldn't win back the US Open either.
With his world ranking plummeting to 11th, Murray now faces a huge fight to qualify for the ATP World Tour Finals next month. One of his opponents for one of the eight places is Berdych.
The 29-year-old currently occupies one of the spots that Murray needs, and it could have been a double victory for Berdych if he had landed Lendl.
However, the Wimbledon finalist of 2010 admitted the 54-year-old wouldn't be his new coach.
"I had a great time talking about tennis with Ivan Lendl today. Result? Ivan would like to help me but he is too busy," he tweeted to his 100,000+ followers.
Indeed Lendl has revealed recently that he will only go back to coaching under the right circumstances, and it looks as though his schedule won't allow him to join up with world no.7 Berdych just yet.
"I've had a lot of enquiries. Eventually, when the time and situation are right, I will do it again," he said to SkySports before Berdych's announcement.
"There are so many things to coaching which I don't enjoy: the travel, the airports, being on the road for so long.
"I don't like doing anything in half-measures so, in order to do it properly, it takes a lot of time. That's the hardest part."
Lendl has established himself as one of the most sought after coaches on the circuit, not only due to his work with Murray, but also because of the huge success he enjoyed as a player.
The former world no.1 was a fierce competitor in his late-80s heydays. Between 1984 through to 1990, Lendl won eight Grand Slam titles despite competing with the likes of John McEnroe, Pat Cash and Mats Wilander.
While attached to neither Murray nor Berdych, Lendl will no doubt enjoy watching their battle for ranking points in the lead-up to London.
Both are in action this week. Murray is second seed at the Austrian Open and needs elevate himself two places between now and November, while Berdych is top of bill in Stockholm and needs only to consolidate seventh position to book his place.
