The 22-year-old Australian has been without a coach for the past two-years.  

Grosjean last coached fellow Frenchman Richard Gasquet from 2014 up until the end of 2016.

The coach is said to not want a full-time coaching role and will accompany Kyrgios to the major tournaments.

Kyrgios will face Spanish world No.21 Roberto Bautista-Agut in the first round in Rome.
