Novak Djokovic is “a machine” who will get close to Roger Federer’s Grand Slam record and go down as one of the greatest players of all time, or at least so says former British number one Tim Henman. Djokovic, 27, is aiming to lift to his eighth grand slam at next month’s French Open and close the gap on Rafael Nadal and Federer, who have 14 and 17 respectively. Henman, clearly an admirer, said: “It’s the way he’s hitting the ball from the baseline, how aggressively he plays and how he does it with so few unforced errors. “And then his movement and his athleticism – his ability to turn defence into attack is as good as I’ve ever seen. He is a machine.”
