Gael Monfils said he expected a "tough" Australian Open despite claiming his first title of the season on Saturday after he won the Qatar Open by beating Andrey Rublev.

Monfils, returning to action after a knee injury which brought a premature end to last season, said he would still be unseeded in Melbourne and expected a tough draw.

"Australia is definitely something else," said the 31-year-old.

"It's a Slam. I know it's going to be tough because I won't be seeded." 

"It's been a while since I played without being seeded. It's always an advantage in a Slam." 

"It's going to be interesting to see the draw, where I will be. I know I can have a very tough first round."

He may, in fact, still have a slim chance of being seeded in Australia, depending on injuries to top players as well as his move up the rankings following his 6-2, 6-3 win in Qatar.

Going into Doha, Monfils was ranked 46th in the world.

With the new rankings out next week, he is expected to rise to 39, still seven places outside the seedings.

However, injuries to players such as Andy Murray and Kei Nishikori have  already ensured players outside the top 32 will be seeded, including Rublev, and more dropouts would help Monfils.

Rublev is currently the world number 39 but his ranking will rise to at least 33 after Doha.

Injuries to others mean he is assured of a seeding in Melbourne for the season's first Grand Slam which starts on January 15.

Asked about his chances in Australia, Rublev, 20, said he was "more confident" after his showing in Doha.

"I'm happy to be seeded and, of course, I feel a little bit more confident. 

"But we'll see what happens. You never know who you are going to play and there's many guys that are not seeded but they are really, really tough to beat."
