Del Potro admits to struggles in return bid, eyes Olympics
Del Potro, 32, last played competitively 17 months ago and underwent a third right knee surgery in August.
The 2009 US Open champion is still hoping to return, but admitted it had been challenging.
“I am having a hard time coming back. I still stand by the desire that I have to continue playing,” Del Potro told ESPN on Friday.
“The reality is that it is difficult. I’m going to keep fighting as long as I feel like I want to continue.”
He added: “Due to the pandemic, the Olympics Games are next year and I’m excited to be there.
