Murray will play in his fourth consecutive grand slam final when he takes on Novak Djokovic in the Wimbledon showpiece.
Murray was beaten at the All England Club by Roger Federer 12 months ago before defeating Djokovic to win his first grand slam title at the US Open.
Like Lendl, his coach of 18 months, Murray's maiden triumph came at the fifth time of asking and he then went on to lose his next final when Djokovic gained revenge at the Australian Open.
Murray missed the French Open because of a back injury, and fans of the 26-year-old will hope the parallels with Lendl's career do not extend to the seventh final.
Lendl lost his seventh, beaten by Mats Wilander in the French Open final in 1985, however he went on to win seven further slam titles.
The 53-year-old is not surprised by Murray's consistency, telling the BBC: "I can't find a reason why he shouldn't (reach finals). He's so good. When he plays well, he should be getting to the semis and finals."
While Britain waits and hopes for a first Wimbledon men's singles champion in 77 years, Lendl is thinking no further than the match itself.
He said: "My job is not to worry about what it would be like (if he wins), my job is to prepare him and give him the best chance to win tomorrow."
Working with Lendl has certainly helped Murray go up a level, on the court and mentally.
The Czech-born American citizen is one of the most high-profile coaches working on the tour but he is happy to take a back seat and does not see himself as the boss.
"I try to let Andy do what he does best and stay just behind and if I see something I point it out," he said.
"You have to have co-operation of the entire team and understanding with the player when you do things, how you do them and the player has to believe in it. If he doesn't, it's pointless."
If recent matches between Murray and Djokovic are anything to go by, tomorrow's clash is likely to be close.
Murray won their only previous meeting on grass, in the semi-finals of the Olympics last summer, but Djokovic has won the last three matches, most recently the Australian Open final.
Djokovic has not lost in Melbourne since 2010 but Lendl is confident Murray has the tools to improve on his performance in January's match.
Lendl said: "There must have been something wrong (with his performance) because Andy didn't win the match so I must find, and I did find, some things he can do better with.
"I can find points to improve even in the matches Andy wins. Nobody ever plays a perfect match."
