Confident heading to Australia Open
Andy Murray remained on top in the the latest ATP rankings released on Monday, with Doha winner Novak Djokovic in second.
France's Gael Monfils, without even playing, jumped one place to equalise his best ever rank.
Monfils benefited from Croat Marian Cilic's second-round defeat in the Chennai Open.
Meanwhile, Murray has insisted that he is feeling in good shape ahead of the Australian Open.
The 29-year-old was second best in his Qatar Open final meeting with Novak Djokovic on Saturday evening, in what was his first competitive defeat in 29 outings.
"My body feels alright just now, so that's positive," he said.
"I still think there are things I can do better, because I wasn't that clinical on break points this week, which maybe comes with playing a few more matches. I still think I have a chance of winning the Australian Open after last night - I don't think that changes."
