The Aussie involvement in the singles draw at the Australian Open may be over, but there will be a local flavour to tonight's quarter-final between Roger Federer and Jo-Wilfried Tsonga.

Australian coach and Channel 7 commentator Roger Rasheed has been working with Tsonga since October and the Frenchman says the 43-year-old coach has made a huge difference to his game.

"It's just great to be with him," Tsonga said of Rasheed after his fourth-round win over countryman Richard Gasquet on Monday.

"He gives me good advice, so I hope I will continue to play good tennis and hope we'll have some good victory together."

Tsonga was flying solo at the Open last year, when he was knocked out in the fourth round.

He says he feels like a different player this time around with Rasheed in his corner.

"He's giving me an extra motivation," Tsonga said.

"It's great because he's always positive. He want maybe more than me to win.

"He's incredible. So, I try to be at his level and have exactly the same motivation because I think he can move some mountains because he's very motivated.

"Every day when I come to the practice, he's giving me a lot of energy just by his talk, and it's great.

"I'm practicing well. When you work hard and you're focused on what you're doing, you are obliged to improve again. Even if it takes time, for sure I will improve my game."

Rasheed is a well-respected figure in the tennis world, having previously coached Lleyton Hewitt and more recently unpredictable Frenchman Gael Monfils.

Tsonga will need all of Rasheed's nous tonight against Federer, who has been in unbelievable form at Melbourne Park.

The 17-time grand slam champion hasn't dropped a set on his way to the quarter-finals, easily dealing with a tough draw that has included matches with former world No.3 Nikolay Davydenko and young guns Bernard Tomic and Milos Raonic.

Incredibly, the Swiss champion is yet to have his serve broken in four matches.

Tsonga has also been in impressive touch, dropping just one set.

But he will have history against him, with Federer holding an 8-3 record over his French challenger, including wins in their past four meetings.
