BERLIN: Roger Federer is practising pain-free after undergoing two knee surgeries this year and says he expects to return to the circuit at the Australian Open in January.
The 39-year-old Swiss reached the semi-finals at Melbourne Park at the start of the year but missed the rest of the season after undergoing a second arthroscopic procedure on his right knee.
Federer told media,"I'm gradually coming back but I'm going to take my time and don't want to put any pressure on myself. I will only take part in a tournament when I am 100% fit. (Agencies)
