The world number two has enjoyed the best moments of his career under the guidance of Lendl, winning Olympic gold and the US Open in 2012 and then Wimbledon the following year, before the pair split in March 2014.
But now they are back and will be aiming to add to a glittering set of achievements:
LONDON OLYMPICS 2012
Murray’s Olympics success on home soil was at the time the biggest win of his career.
The Centre Court London 2012 final against Roger Federer came four weeks to the day since he lost to the same opponent in the 2012 Wimbledon final.
But Murray wasn’t going to be beaten by the Swiss maestro for a second successive time on grass.
Indeed, it was a stroll in the park for the Briton who lost just seven games against the World No.1 on his way to a 6-2 6-1 6-4 victory in front of a buoyant home crowd.
It was an early indication of the mental strength Lendl had given Murray to get over the line in big matches.
US OPEN 2012
This was Murray’s breakthrough Slam victory working with Lendl and it proved he made the right decision to hire the Czech legend.
After defeats in his first four Grand Slam finals, Murray nailed Rafael Nadal in the semi-finals to set-up a final clash at Flushing Meadows with Novak Djokovic.
The Scot overcame the Serbian star in five sets, blowing a two-set lead, only to fight back and win his maiden major with a deciding set score of 6-2.
WIMBLEDON 2013
Murray became the first British winner of the men’s singles title at SW19 since Fred Perry in 1936, ending 77 years of heartache for tennis fans in the UK.
A year on from his tearful post-match interview break down after losing to Roger Federer in the 2012 final, Murray dismissed Novak Djokovic, again, in three straight sets.
This was Murray’s last slam win and of course both of these arrived under the stewardship of Lendl.
Even though Lendl is known for his fiery personality on the court, the two hit it off from from the first training session and enjoyed many funny moments together – none more so than this incident during a charity match at Queen’s Club:
