Ivan Lendl believes that Andy Murray's US Open triumph could lead to the Scot winning many more Grand Slam titles.
Murray became the first British man to win a Grand Slam since Fred Perry in 1936 when he overcame Novak Djokovic in a brutal five-set encounter which lasted just seven minutes short of five hours.
The 25-year-old eventually prevailed 7-6 (12-10) 7-5 2-6 3-6 6-2 to write his name in the history books and Lendl, who became his coach at the start of the year, is confident that this will be the first of many.
"Hopefully, we're not anywhere near where Andy can get," Lendl told the BBC. "I didn't come here to have a good time - I came here to help Andy win. He did, so it's job done."
Murray shares many traits with his coach and will now be hoping he can emulate the achievements of Lendl who lost his first four Grand Slam finals before going on to win eight majors.
It has been an incredible season for the Brit who was beaten in the Australian Open final by Djokovic, before losing in the quarter-finals at the French Open.
There was more heartache at Wimbledon after losing to Roger Federer in four sets but he was soon able to exact revenge after beating the world number one to win gold at the London Olympics.
With a silver medal in the doubles with Laura Robson, Murray entered the tournament at Flushing Meadows full of confidence and Lendl believes his experiences over the previous 12 months will help him win many more major titles.
"One of his most important matches of the year, maybe the most important, was his loss to Novak at the Australian Open, because that was war just like tonight," said Lendl.
"That gave him the belief that he can hang with these guys and it showed him what it would take to win. It didn't catch him by surprise.
"Go back to the Olympics - he has already won a big one. He won two big ones in this fantastic year. I'm very happy for Andy. It's a great achievement and let's hope he can continue and rake up more.
"Andy has been maturing very nicely as a player, as a competitor, as a person. As you mature you become more comfortable in these situations.
"Of course, it's very important to be in more of these situations and the more of them you are in the more comfortable you feel."
