"It helped them to maintain a high level and go over their limits" - Patrick Mouratoglou on the epic 2012 Australian Open final between Nadal and Djokovic

Novak Djokovic and Rafael Nadal have had numerous historical duels since 2006. However, one encounter marks the pinnacle of their rivalry, as they never pushed each other to the limits as in the 2012 Australian Open final.

Djokovic prevailed 5-7, 6-4, 6-2, 6-7, 7-5 after five hours and 53 minutes, celebrating in the most extended Major final. Renowned coach Patrick Mouratoglou recalled the clash and called it the most demanding duel in tennis history, both physically and mentally.

Mouratoglou praised their mental strength, allowing them to go over the edge and push each other to the limits for six hours.

"Novak Djokovic and Rafael Nadal went beyond their physical limits," he said. "They are probably the best players in the game's history when we talk about mental strength. It helped them to maintain a high level and go over their limits. It was one of the most mental matches in tennis history. They refused to surrender, and their minds brought them over the edge.

"They were at their best physically, but that alone would not be enough to keep them on the court for almost six hours without dropping the pace. Two other physically prepared players would have cracked earlier due to the lack of mental aspect.

"Novak and Rafa had it, and it allowed them to go that far and challenge each other."
