Andy Murray has carried out the second overhaul of his coaching team this year after axing Dani Vallverdu and Jez Green.

The move is a statement of faith in Amelie Mauresmo, whose future as Murray's coach had been called into question ahead of the 2015 season.

Murray and Vallverdu met at the Sanchez-Casal Academy in Spain more than a decade ago and the Venezuelan took on a key role in the coaching team.

He was highly valued by Murray's former coach Ivan Lendl, while Green had been part of team Murray for seven years. Both were reportedly unhappy when Murray decided to appoint Mauresmo as Lendl's successor in June.

Mauresmo's position has been under scrutiny from the start and Murray's hammering by Roger Federer at the ATP World Tour Finals earlier this month led several pundits, including Tim Henman, to urge the former Wimbledon champion to look at his team.

Murray has clearly done that, but it is two long-serving members rather than Mauresmo who have left. Murray said: "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."

Murray will begin looking for a replacement for Vallverdu immediately, while his other long-time fitness trainer Matt Little could travel more with the Scot following Green's departure.

Murray flew to Manila last night to play in the inaugural International Premier Tennis League and will travel to Miami next week. His 2015 season starts with an exhibition event in Abu Dhabi on January 1.
