Roger Federer, who can get to No. 1 by reaching the semifinals this week at Rotterdam, acknowledges that he's chasing a return to the top ranking.
"I'm hoping to get to No. 1, and hoping to do it this week," he told press at Rotterdam, as quoted by AFP. "The achievement would be quite incredible."
Federer had not originally been scheduled to play but joined the field a few days ago by taking a wild card. His relatively straightforward Australian Open victory left him just behind No. 1 Rafael Nadal in the rankings, and sufficiently fresh to return to competition in just two and a half weeks.
"I didn't expect to win Australia, I played it not thinking about No. 1," he said, but then added that he saw his opening at an event he had frequently played in previous years. "I thought, I could always play Rotterdam, I'd love to play... I'm here, healthy and eager to play."
