LONDON (AP) - Roger Federer has set a goal of winning at least 20 Grand Slam titles before he retires.

The 29-year-old Swiss added his 16th title with a victory at the Australian Open this year. But he failed to get beyond the quarterfinals at the French Open and Wimbledon. He’s dropped to No. 3 in the rankings, his lowest position since November 2003.

However, Federer told the BBC that winning 20 majors is “is something doable for me.”

Federer overtook Pete Sampras’ record of 14 Grand Slam titles at Wimbledon in 2009. By winning the French Open a month earlier, he became only the sixth man in history to win all four Grand Slam titles.
