Roger Federer expects tough game against Grigor Dimitrov and said that should give the best of yourself if you want to skip the third round of the Australian Open. The match between the two will be on Friday.

"Frankly, heavy rival for me. He has the qualities and can be really dangerous. Physically well prepared for five sets, so you have to show the best of myself on the court on Friday, "said the Maestro.

"It is difficult to evaluate our match in Brisbane because I had some problems and tried to pass through the games without too many rallies. So, when I look back at those meetings, it is difficult to decide what was good and what is not so, "said Federer.

Last week, Dimitrov reached the final in Sydney, which missed a match point in the tiebreak of the third set and lost to Serb Viktor Troicki.

"I think he played well in Sydney and this tournament can definitely increase his confidence, if you take the positives from his performance, because to lose in the final, having had match point, not very pleasant. It had to go through similar situations and they are the worst. But if you look at things positively, Grigor could and should have won the tournament. So, he is currently in an ascending line, "said Federer.
