• Serbian will soon be the only active member of ‘big four’
• 24-time grand slam winner overwhelmed by Nadal exit

Novak Djokovic said he felt overwhelmed at the news he will be the only active member of the so-called big four.

With Roger Federer and Andy Murray having already left the sport, Rafael Nadal announced on Thursday that he will also hang up his racket at the end of the season. Djokovic has spent nearly two decades battling his biggest rivals, having recorded the most grand slams of them all, 24, compared to Nadal’s 22, Federer’s 18 and Murray’s three. The Briton, of course, lost eight grand slam finals, all to one of Djokovic or Federer.
