“When you are going on court every day without the clear goal because you cannot move well, you have pain, then is a moment to take a decision,” Nadal said of Murray’s decision.
“I didn’t arrive to that point. I am a positive guy. I always had the feeling that we’ll fix it. But, of course, there are periods of time that you don’t see the light. It’s tough.”
For as long as the 33-year-old believes he can haul himself back to contend for Grand Slam titles, his motivation remains resolute. Only three shy of Roger Federer’s tally, it is a record the Spaniard would feel is well within reach, pending fitness and health.
“Even if a lot of days you go on court when you have troubles or you go to the gym without having a real goal or without knowing why I am going there, because I don’t see a benefit on this day, you keep going,” Nadal said.
“That’s the only way that you can keep having confidence and hope for a good comeback in terms of health.
“I know sometimes it’s hard mentally. It’s tough when you have one thing, then another thing.
“But I know that tennis is not forever. I want to do it as long as I can and give myself the best possibilities to fight for the things really I am passionate about.”
