Andy Murray's already disappointing 2014 season came to a horrific end at the ATP World Tour Finals and, as expected, the British no.1 has been forced to make changes to his coaching staff.
Two sackings have been made with his assistant coach, Dani Vallverdu and fitness trainer, Jez Green, both making way.
It means that main coach Amelie Mauresmo is set to keep her position. The Frenchwoman has been said to have been at odds with Vallverdu in the past, so the latter's dismissal will come as a boost to her.
Murray revealed the news by virtue of a statement as he prepares to take part in the new International Tennis Premier League - dubbed the T20 of tennis - it read: 'We sat down at the end of the season and decided that a change would be best for all of us,'
'My off season training and Australian Open preparations have already begun and I am very excited for the new year. I thank Jez and Dani for all their hard work over the years and wish them the best for the future.'

The news comes as something of a shock, as many expected Mauresmo would be the person to be moved on in the light of some poor results in their partnership. As it is, the 27-year-old has removed two of his longest-serving assets.
Both Vallverdu and Green have been with the two-time Grand Slam champion for over five years - the latter for seven - and were part of the successful team who guided Murray to his two biggest career titles, headed by Mauresmo's predecessor Ivan Lendl.
Questions were raised over the functionality of the new regime after Murray's shock quarter-final thrashing at Wimbledon this summer. Whilst trying to defend his SW19 crown, Grigor Dimitrov eased to a straight-sets win on Centre Court against an anguished Murray, who appeared to lash-out at his team on-court during the loss.
Vallverdu especially was apparently upset over the appointment of Mauresmo in the first place. The Spaniard, who has become a great friend of the Briton's during their time together, was kept in the dark at Murray's intentions to become one of the highest-profile male stars to employ a female coach.
The so-called spat was quelled before the US Open when they were all pictured together in high spirits, but results didn't improve.
Murray lost out in Flushing Meadows, the tournament he won in 2012, and had to scrap his way to the ATP Finals - only to be knocked out in the group stages by courtesy of losses to Kei Nishikori and Roger Federer; the latter inflicted the heaviest defeat of Murray's career.
Ahead of the 2015 season, rumours had been circulating that Murray could link up with John McEnroe or return to Lendl, at Mauresmo's expense, but today's news looks to have quashed those chances.
