Andy Murray believes coach Ivan Lendl's bittersweet relationship with the US Open could help him unlock the door to lifting his first grand slam title.
Murray reached his eighth straight quarter-final at a major with a 6-4, 6-4, 6-2 win over big-serving Canadian Milos Raonic as he tries to end four grand slam finals without a trophy.
Lendl, who started to work with the third seed at the start of this year, lost three finals in New York from 1982 to 1984 before clinching three titles in a row from 1985 to 1987.
Olympic champion Murray was runner-up to Roger Federer in the 2008 final in what is his only appearance in the US Open final.
"I've spoken to him about playing in big events, you know, losing to top players in big matches. He went through it himself," said Murray. "So when you have someone like that in your corner, I don't feel bad about those losses.
"I learned much better from, for example, Australia this year compared with the year before, and also Wimbledon this year I learned from much better. I played one of my best tournaments ever at the Olympics, which in the past when I had tough losses I haven't done.
