Novak Djokovic defeated Benoit Paire in straight sets on Thursday. Serbia beat France to reach the quarter-finals. The Belgrade native said: "Maybe from your perspective it was easy, but from ours definitely not. We still have to win matches.
Tsonga is in good shape the last couple of months. Him playing indoors is one of the toughest opponents to play because he loves to play indoors. He's had more success throughout his career indoors. And with that big serve, a big weapon of his, it's never easy to play him.
But I thought Krajinovic played one of the best matches that I have seen him play ever. Very solid. Had so many opportunities, all the time pressuring Tsonga's serve. He was just playing really, really well. Credit to him because also he gave me wings and a little bit of a relief coming into my match that I played against Benoit.
Which I was expecting to, honestly, that they are going to have Benoit instead of Gael. I haven't played Benoit in a long time. I knew that he's got a big serve, a lot of talent. He's got a lot of abilities to do different things.
But he's unpredictable as well. So I think I was solid. I was just focused and just trying to stay in the match mentally as well every single point, which probably decided the winner in the end. And this is the most ideal scenario for us.
Winning both ties after singles and not being really pressured by the doubles, which would be a complicated thing for us against France, which has the best doubles in the world at the moment. So we're coming into quarters now and playing against Russia tomorrow. That's definitely one of the best quality teams here. It's going to be a big challenge."
