Andy Murray admits that his partnership with coach Ivan Lendl could last another four or five years.
Since Lendl became involved with Murray towards the end of 2011, the Scot's game has certainly moved up another notch.
In a landmark season for the 25-year-old, Murray became the first Britain to win a Grand Slam title for 76 years, was the first Brit to reach a Wimbledon final since 1938 and added gold and silver medals for good measure from the London Olympics.
And Murray admits his partnership with Lendl - himself an eight-time Grand Slam champion - has worked well.
He said: "Ivan and I have a very good relationship, it's very honest and open, that's why it has worked so well and why both of us are planning long term.
"We spoke at the end of last year and it was much more short term, such as 'let's see how the first few months of the season go'.
"Now it's, 'What are we going to be doing in four or five years' time?"
Murray also admitted that his successes during 2012 have given him greater confidence.
He added: "Since the Olympics I just feel a bit better about myself. I find it easier to walk around with my head up, whereas before I was always head down, not wanting anyone to see me or say anything.
"Maybe I felt that having lost in Grand Slam finals I was letting whoever it was down.
"I had been reminded every day for the last six years that it's this long since someone from our country won a slam!"
