Andy Murray, who lost to Novak Djokovic in the semifinals of Indian Wells, admits that over the past couple of years he has not playing well enough against his main rivals, Roger Federer, Rafael Nadal, and Djokovic. The last time he defeated any of those three was in 2013 at Wimbledon, against Djokovic in the final. A few months later, Murray underwent back surgery.

Murray lost to Djokovic in this year’s Australian Open final, and has lost his last six matches against the Serb. The world No. 4 has lost his last three matches against Federer and his last two matches against Nadal.

“Look, in Australia felt like I was extremely close,” Murray said. “I didn't feel like the difference was necessarily in the level of the tennis. I didn't feel like there was a difference. My consistency over the last couple of years is something that hasn't been as good as I would have liked, whereas the guys ahead of me have been much better—especially in the Masters Series events, which, earlier in my career I was better. I played better in these events. So that's something I need to try to do a little bit better when I come up against them in these tournaments. That's for sure.”
