After playing Doha, Roger Federer now has the data he needs to get himself 100% by Wimbledon. That’s his goal.

Federer admitted that he didn’t want to play the Australian Open because he didn’t think he could win it. And following a loss today in Doha, maybe he feels that his not strong enough to win Dubai, so he withdrew from that event.

Now the focus, he says, will be squarely to be ready for the grass season which is the 39-year-old’s best shot at another Slam.

“I might be better earlier, but that would be a bonus and that means I’m at 100% much before Wimbledon,” Federer said Thursday.

“When I took the second surgery I was definitely eyeing more for the Australian Open or something at that point. But when I saw the progress was slow and I had to be careful and I had lost all muscles basically, we knew that we’re going to pick a schedule that’s going to make the Australian Open really close,” he said. “I could have played the Australian Open like this but worse, and I’m not winning the Australian Open this way. That’s why there is no point of going there.

“Now after doing what we were able to really do, finally play some points and now play a match, I knew and we knew that I still need another five, six weeks in fitness, probably a little bit more down the road.

“So in those next, I don’t know how many months that is till Wimbledon, maybe four months or so, I think we’ve just got to take a real good look at the schedule and see when we do the fitness with Pierre, what I still need to do in terms of rehab with Danny, my physio, and then with the tennis coaches and just see how much workload can the body and the knee still take and what’s the best way to prepare all the way for basically the beginning of the season for me, which is the grass court season.”

That won’t mean Federer will not play on the clay.

“I think matches are important,” Federer said. “What comes before the grass courts are the clay courts. So from that standpoint, I have no choice but to play on clay if I want to play matches.

“I assume I will play some clay, you know. The question is what. We have a vague idea, but we said let’s wait for Doha and potentially Dubai to potentially make any decisions for that, and fitness comes first and then we’ll see what comes after.

“At the end everything is geared towards the grass. So whatever makes me be 100% there, I will do.”
