Roger Federer has admitted that his days on the court are numbered.

Turning 37 in August, you would have been forgiven for thinking the Swiss superstar would have started to slow down in the twilight years of his career.

With three Grand Slam victories in his last four entries, an entirely different tale is told.

However, the Basel-born titan of world tennis knows he can’t last forever.

Federer said:

The end is closer than ever. But when it will be, I don’t know. I don’t want to have real plans.

One thing is sure: my life will still be interesting and funny after, especially with my four children. But as they get older, things become more serious, for example with school. I am looking forward to it.

The 20-time Grand Slam winner went on to say:

It’s a little bit strange: in the past, you spoke about a young player when one like Borna Coric was beating some important players.

Now I feel that if you don’t beat Rafa (Nadal), me or (Novak) Djokovic, no one almost cares about it.

The humility of Roger Federer has characterised his entire career to this point, and he was typically meek in assessing his career:

I never thought as a kid that I would enter history books. The goal was to be the best possible: it’s not normal, it’s not reality.
