Simona Halep recently announced she will reunite with coach Darren Cahill. Cahill was Halep's coach for four years before they ended their partnership at the end of the 2018 season.

Cahill stated the travel requirements were forcing him away from his family for too long, and needed a break. 

But now, Cahill is ready to join forces with Halep again and will be by the Romanian's side next season. The two have established a great relationship on and off the court, as proven by their Instagram accounts.
