On whether Murray represents a threat to Federer, Nadal and Djokovic, Henman then said: “The challenge, with the best-of-five matches, is huge, but we all know that with Andy if you say he can’t do something he likes to prove people wrong.
“I think it is very unlikely but I would never with all these top people… write them off.”
And Rusedski added: ”If you say he can’t do that, it motivates him more.”
Murray, meanwhile, is full of respect for the level that Federer, Nadal and Djokovic continue to play to at the respective ages of 38, 33 and 32.
“I honestly haven’t really thought much about [it],” he said when asked if he thinks he can prolong his career as long as Swiss legend Federer.
