‘I guess for me as an athlete, just to know that I have got that person there that can overcome and have that shoulder to lean on whenever I need, that is what I love about her,’ he said. 

It comes after this weekend’s The Sunday Telegraph reported Nick has ‘purchased a $1.6million penthouse in Sydney’s Kensington to be with girlfriend Costeen Hatzi’ when he’s not travelling the world for tournaments.

The three-bedroom, two-bathroom apartment boasts wraparound glass walls offering sweeping views of the city, as well as a rooftop wet bar and two car spaces.
