Roger Federer has admitted making serious errors in his planning which contributed to a disastrous 2013 campaign but he insists retirement is not on his agenda.
The 17-time grand slam winner has slumped to No.7 in the world and eighth in the race for the ATP World Tour Finals, and failed to make a final at any of the four majors, a run of disappointments that has led many to predict the end of the road for the 32-year-old.
The Swiss, who split last week with coach Paul Annacone after more than three years, confessed that he could have done things differently, like playing matches he should never have played.
But he's set his sights on the Rio Olympics, by which time he'll be 35, and maybe even beyond.
