Double Australian Open champion Jannik Sinner set his sights on mastering clay and grass courts to make himself a complete player after the Italian claimed his third hardcourt Grand Slam title on Sunday.

Jannik Sinner expects it to take some time before he can replicate his dominance on hard courts at Wimbledon. The world number one made it three grand slam titles in a row on his favourite surface by successfully defending his Australian Open crown with a straight-sets victory over Alexander Zverev.

A dark cloud has hung over Jannik Sinner ever since it was revealed he failed two drug tests for a banned steroid last year, but it hasn't stopped the Italian from playing dominant tennis and winning another grand slam event.
