? Rafael Nadal: 18-year top-10 veteran

Rafael Nadal first broke into the world top 10 on April 25, 2005 — and the 22-time major winner has been there ever since.

He was just 18 at the time; now he is 36.

Nadal has also spent 209 of those weeks as No 1, first reaching the summit in August 2008.

The Spaniard's spell in the top 10 has stretched over 900 consecutive weeks, a feat that not even Novak Djokovic or the now-retired Roger Federer can boast.

Only women's legend Martina Navratilova, with 1,000 weeks in a row inside the WTA top 10, can better Nadal's astonishing longevity.

Navratilova was ranked in the top 10 from the first computerized ranking on Nov 3, 1975 until Dec 26, 1994.
