Bjorn Borg has predicted that Andy Murray will be challenging Rafael Nadal and Roger Federer for the Grand Slam titles next season.
The Swede secured five Wimbledon and six French Open crowns between 1974 and 1981, winning a record 41 consecutive games in the former tournament, and is one of the icons of the game.
Murray has made startling progress this year, winning five tournaments and reaching the final of the US Open only to be beaten in straight sets by Federer to move up to fourth in the rankings.
Borg told BBC Radio Five Live: "I said last year Andy Murray was going to be a great player.
"Everybody was a little bit sceptical when I said that. But look at what Andy has been producing this year.
"He is improving his physical condition and his mental aspect.
"He is one of the top players, he has been winning the Masters Series and he knows he can beat every single player in the world.
"I pick Federer, Nadal and Murray to win Grand Slam tournaments next year."
