Darren Cahill says this is his last year guiding the career of returning world No.1 Jannik Sinner - but if the Italian star's co-coach has his way, the "special" Australian will stay in their team for the next five years.
Supercoach Cahill, who's mentored four world No.1s in the shape of Andre Agassi, Lleyton Hewitt, Simona Halep and now Sinner, has announced he'll retire at the end of the year.
But as the 23-year-old prepared to make his tennis comeback on Saturday at his home Italian Open after serving his controversial three-month ban for doping, his co-coach Simone Vagnozzi sounded as if he had some hope that Cahill could be persuaded to stay with 'Team Sinner'.
