Argentine star Juan Martin del Potro will have a new coach working alongside him once the COVID-19 pandemic is over.

The 2009 US Open champion confirmed on Saturday that he parted ways with coach Sebastian Prieto, whom he has worked with since August 2017.

Prieto is set to switch to coaching fellow Argentine Juan Ignacio Londero.

“I want to share that I have agreed with Sebastian Prieto to end our partnership, so that he can work with Juan Londero, while I continue my rehab process,” Del Potro wrote on Instagram.

“I’m very thankful to Piper for all of these years together. He is a great coach and an even better person. All the best!”

Del Potro did not onfirm who will replace him.

He has not competed since last year after undergoing surgery to repair a fractured right kneecap he sustained at the Fever-Tree Championships in London.
