If Murray makes the final in Paris, he's world number one.

It's all in his hands now. pic.twitter.com/aXlNpsfRHP

Djokovic OUT. Murray becomes world No 1 if he wins two more matches to reach Paris final. Plays Berdych later & poss Tsonga/Raonic tomorrow.

This is the moment to remind the tennis world that Djokovic from Jan 2015 to June 2016 is the best tennis has ever seen. Don't forget it.

If I was #Novak I would walk away from this season like #serena did and come back in 2017 ready to play tennis . Andy is now the man to beat

Marin Cilic finally beats Novak Djokovic on his *15th* try, 6-4, 7-6(2). Now 1-14. into Paris SFs vs Isner.

Murray just two wins from #1.

And just to think, this massive swing between Djokovic and Murray doesn't even include Olympics, where Murray got gold and Djokovic lost R1.

#Djokovic loses to #Cilic in Paris#Murray world No.1 if he reaches the final. In the same year that brother Jamie was Doubles no.1

Class

Seeing #Nole win is great, but seeing him lose with such chivalry is just priceless. #teamnole #tennis #bnpParibasMasters
