Roger Federer believes that his upcoming match against Andy Murray at the Australian Open will be a "good" contest.
The Swiss pro will play Murray for a place in the semi-finals of the Grand Slam after beating Jo-Wilfried Tsonga in the fourth round.
"I'm looking forward to playing against Andy," BBC Sport quotes Federer as saying. "I hope physically he's doing well.
"We always have good matches. He has a much better backhand than I have so it's up to me to figure it out."
Murray reached the quarter-finals with victory over Stephane Robert.
