Their moment at the net after the five-set match was done says it all. (AP)

"This photo says it all," wrote Juan Martin del Potro on his Instagram page. Earlier that Wednesday, on Centre Court at Wimbledon, the Argentinian had lost to Rafael Nadal after being up by two sets to one. 

Their quarterfinal match would rage on for nearly five hours, finishing in the waning daylight: 

The 7-5, 6-7 (7), 4-6, 6-4, 6-4 epic ended with an embrace, after Nadal walked over to Del Potro's side as he lay on the grass after losing his footing. 

"After almost five hours match, I fell down. I wanted to stay there for all night long," Del Potro said. "But Rafa cames to me and we made a big hug, and it was kind of him."

The unforgiving match had sent Del Potro tumbling to the grass on more than one occasion.

While Nadal put in so much effort he literally ran out of court space.
