It is hard to argue with the statistics on this one, Murray has won all of his Grand Slams under Lendl (3), in a time when he also won two Olympic golds.
He has been a permanent fixture on Murray's coaching team since a year ago - with Lendl on a more part-time basis - and he will likely be the man in Murray's corner when the new season begins.
The British number one announced the parting of ways on his official website, describing the move as "mutual".
Their reunion proved just as fruitful, the 30-year-old winning a second Wimbledon crown, successfully defending his Olympic title in 2016 and ending that year as the world No.1.
Murray intends to be ready for the start of next season in January, when the Australian Open is played, saying Friday: "My focus now is on getting ready for Australia with the team I have in place and getting back to competing".

World's First Human Head Transplant Successfully Carried Out, Claims Surgeon
Technically, the head would be the recipient, as the donor would be the person who is brain dead giving up their healthy body. The paper will be released in a few days. "Everyone said it was impossible, but the surgery was successful".
Lendl said, 'I wish Andy well going forward.
Lendl will continue to work in the field of player development at the US Tennis Association, where his group's Patrick Kypson recently won his first professional event.
The first time they split was in March 2014 but the team was re-formed not long before Murray won his second Wimbledon in the summer of 2016. That includes, most famously, the Scotsman's 2013 title at Wimbledon, which made him the first British man in 77 years to win the singles championship at the All England Club.
The top of the men's game is now beset by a glut of injuries to big-name players, with Murray, Djokovic and Stan Wawrinka all missing from the ongoing ATP Finals in London, which Murray won a year ago. "We had a great run and a lot of fun", said Lendl, who has been widely credited as one of the main keys to Murray's top-level success.
Hopefully, this decision will be out of Murray's mind as he looks to get fit and prepared for the 2018 season, a season he will be hoping he can challenge for that world number one position once again.
