Wayne Gretzky has challenged Dustin Johnson to follow the example of Tiger Woods as the U.S. Open champion seeks to follow up the best year of his career to date.
Victory at Oakmont in June saw Johnson finally break his major duck, after a number of near-misses in golf's premier events.
Johnson also claimed high-profile wins at the WGC-Bridgestone Invitational and BMW Championship in 2016 and was named the PGA Tour's player of the year, having also helped the United States to victory in the Ryder Cup.
Ice hockey great Gretzky - the father of Johnson's fiancee Paulina - is now hoping the world number three can reach even greater heights next season.
Gretzky told GOLF magazine: ""If I scored 50 goals in a season, I wanted 70 the next year. If I got 70, I wanted 90. Never, ever settle.
"I've told Dustin he has to be more like Tiger. I don't mean he has to be Tiger - you only get a few athletes like that a century - but part of what made Tiger Tiger was relentlessness.
"Dustin just won three tournaments and [one of those was] a major. That's a great year.
"Now go win five tournaments and two majors. I want him to see that only he can put limits on himself."
