It was at an Under-16 Championships in Andorra that brought the two together, and during Andy Murray's rehab, Rafael Nadal has been showing his support.
Sir Andrew Barron Murray OBE (yes, his middle name is Barron) has not played competitive tennis since the start of the year, when American Ryan Harrison beat the Scot in the round of 16 at the Brisbane International.
Since then, Murray has undergone hip surgery and after many delayed talks of a comeback to the sport in time for this month's grass-season, Murray is finally looking like he's nearly ready to compete with tennis' best.
During his time off, the current world no.1 Rafa Nadal has been showing his support for the sidelined Murray, and has offered words of wisdom on how to regain that peak form.
Murray, 29, was pictured this week on the training courts, and after announcing that he won't take part in next week's Libema Open in the Netherlands, he is set to make a decision on whether he will play at Queen's later this month, with Wimbledon at the start of next.
The two-time Wimbledon winner is also looking ahead to the China Open at the back-end of September:
"I look forward to returning to Shenzhen to play at this year’s Open. I enjoy playing in China and I always appreciate the crowd support out there. I have some great memories from the last time I played, especially the final, so hopefully I will have a good run this year,” he said.
Nobody will be willing Murray back to full-fitness more than his mother Judy Murray.
Mother, tennis coach and motivator, Judy has been there for Andy since day one, and told the story of her son came to meet and bond with Nadal
It was a fateful night in Andorra when Murray and Nadal's love blossomed, with Murray phoning home to blight his own training facilities compared to that of the Spaniard's.
But, this eventually led to him joining a Spanish tennis academy.
If the two didn’t compete in Andorra all those years back, Murray may not have moved to Spain and become the tennis player he is today.
Hopefully, though, the two will one day compete again.
