Murray then visited the academy’s museum, with Nadal serving as the three-time Grand Slam champion’s guide. But, having been walked through various rooms dedicated to the tennis legend’s past, one moment in particular showcased Nadal’s humility and modesty.

A member of staff came over to Murray and told him Nadal was not comfortable with the presence of a room dedicated to the Big Three - himself, Novak Djokovic and Roger Federer - within the academy.

He explained: "Rafa won’t tell you, but he doesn’t feel good because we have a room about the Big Three. He won’t tell you but…"

Murray responded graciously, saying: "That’s fine," as the staff member re-iterated: "I know it’s fine for you but he told me like… because it was not his decision to make. He won’t tell you." The Brit replied: "No, no, that’s fine. It’s not a problem."

Murray spent his entire career as the fourth man chasing three of the all-time greats. The fact he still managed to become world No.1 and reach 11 Grand Slam finals in such a dominant era is testament to his own skill, which has often seen them described as the ‘Big Four’.

The slightly awkward moment didn’t ruin Murray’s visit, either. "I love going around the museum. For me, that was the best part of it," the 39-year-old said in the episode.

Murray and Nadal appeared comfortable talking to each other throughout the video, having known each other for over two decades. Even though Nadal leads their head-to-head 17-7, he once said that Murray was the only player who came close to the standard of the Big Three.
