Novak Djokovic says he would not regard it as a surprise if he wins his battle with Andy Murray and returns to the top of the world rankings just two weeks after surrendering his No 1 status. Djokovics 122-week reign as No 1 was ended by Murrays success at the Paris Masters, but the race to secure first place in the year-end rankings is set for a dramatic conclusion at the ATP World Tour Finals, live on Sky Sports.

To me, that wouldnt be a surprise. Andy Murray will be hoping to retain his world No 1 status Djokovic has lost just one match at the Tour Finals since 2012, while Murray has never reached the final.The Scot might not be best placed to hold off Djokovics charge as he will have to play three days in a row following his three-hour marathon win against Nishikori on Wednesday, while his rival benefits from a recovery day. Thats obviously something that you wish for as a player, to have everything in your hands, not to depend on other players, added Djokovic.In this particular case, Im glad that its like that. Everything has been going in a positive direction. Djokovic says players should be given warnings before they are given time violations by umpires Ive been playing better and better as I proceed in the tournament. I have now a day of rest.Its the last couple matches of the year, hopefully.
