After winning at Indian Wells last week, world number one Novak Djokovic can extend his lead at the top of the world rankings with a title in Miami this week.
The Serb beat world number two Roger Federer in the title match at the BNP Paribas Open and will attempt to repeat a rare March trophy double at the hard-court event in Florida, ahead of the start of the claycourt season.
With Federer opting out of the event in favour of holidaying with his family, Djokovic can extend his lead over the Swiss ace, while second seed Rafael Nadal and number three Andy Murray can also add more rating points before the switch to Europe next month.
Over the last decade the so-called 'Big Four' has been a class above the rest of the players on Tour and Djokovic is eager to add any competitive edge over his rivals to his game.
Federer still leads the way with 17 Grand Slam titles with Nadal on 12. Djokovic is closing the gap to the Spaniard with eight titles at the majors, while Murray can boast with two.
"We still keep on pushing and moving the borders," Djokovic said ahead of this week's event.
"We still keep on improving, all of us.
"We are playing better than we did a few years ago, and it's because of these rivalries. That's something that is special in our sport.
"I've got to look forward to get to Miami and have a dinner with Boris [Becker, his coach]. I think it's on him this time. I surpassed his 49th title, so that gives a little bit of special spice to this title."
Nadal lost in the quarter-finals of Indian Wells to Milos Raonic, but with points from his final run in 2014 to defend, the Spaniard is confident of a better performance in Miami this week.
"Sometimes with losses like I had few times in the last couple of weeks, maybe you are going down, but is not my case. I think every week I am better," Nadal said.
"Every week I am more competitive. Every week I feel stronger, quicker on court again. My movements are good again."
