Andy Murray completes golden era's 'Big Four', insists Djokovic
Five-time grand slam winner says Britain's new Olympic champion is part of game's 'golden era'
It has been an ongoing debate in the tennis world - does the current "golden era" for the game feature a "Big Three" or a "Big Four" including Andy Murray?
Some have argued only three - Roger Federer, Rafa Nadal and Novak Djokovic - count, given that Murray has yet to win a grand slam tournament.
But after the Briton's heroic showing in defeat by Federer in the Wimbledon final and then his Olympic final triumph over the Swiss world No 1, the question is being posed anew.
Talking of the "golden era" the game is going through, five-time grand slam singles champion Djokovic casually referred to a leading four. "You have four players who are I think winning 90 per cent of all the major tournaments that you have on the tour," the Serb said ahead of his opening match at this week's Cincinnati Masters. "I mean, so many titles and so much competition going on and so many great rivalries, great matches, history and all these things that are, I think, making this era a golden era."
But does that make for a "Big Four"?
Djokovic seems to think so.
