Like Rafa, Andy has been speaking about their quarter-final, and like Rafa, he's been paying tribute to his opponent.
Speaking to Jim Courier on court immediately afterwards, Andy spoke of his disappointment at Rafa's retirement with injury.
"I've known Rafa since I was 13 or 14 and he was someone I always looked up to," said Andy. "When I was coming through the juniors he was already playing the seniors and he's my favourite player to watch, just because of what he brings to the court - his energy. I was gutted for him."
"It just all happened so sudden," he added in his press conference. "There was one backhand in the following game he didn't quite run for. I didn't realize it was such a big problem. I was very surprised because I've seen Rafa play matches where he's obviously been in a lot of pain and discomfort, and he's played on.
"Here last year he won back‑to‑back five‑set matches in the semis and finals. His knee is obviously sore enough that what happened last year, he had to miss Wimbledon. That's a shame, because I obviously don't know how bad his knees are."
