Roger Federer has won his 100th ATP Tour title at the Dubai Tennis Championships – 6,600 days after winning his first in Milan.

The 37-year-old Swiss – a 20-time Grand Slam champion – beat Greece’s StefanosTsitsipas 6-4 6-4.

Federer’s first ATP title came at the Milan Indoors on 4 February, 2001, when he beat Frenchman Julien Boutter.

He is just the second man, after American Jimmy Connors in 1983, to reach the landmark.

Federer will have to win 10 more titles to beat Connors’ men’s record of 109.
