Top Five Must-Watch Storylines Unfolding at the French Open.

All eyes are on Rafael Nadal as he steps onto the clay at this year's French Open, potentially marking both his triumphant return and his poignant farewell at Roland Garros, where he has cemented his legacy as the tournament's greatest champion.

Nadal aiming for a record 15th men's singles title seems unlikely, especially with Novak Djokovic defending his crown in an open draw.

In the women's singles, three-time champion Iga Swiatek is favored to continue her dominance.

Here are five key storylines to watch as the clay-court major kicks off on Sunday.

Farewell Tour: Nadal and Murray Ready to Bid 'Au Revoir'

While nothing in sports is ever certain, Nadal lifting the Coupe des Mousquetaires has come close.

The King of Clay has dominated in Paris, losing only three of his 115 matches here.

The 37-year-old Spaniard missed last year's tournament due to injury, and with his retirement expected later this year, he is fit enough to return, likely for the final time.

Nadal received a hero's welcome during practice on Court Philippe Chatrier this week, with thousands of fans watching.

How Nadal will fare when the tournament starts is a hot topic, especially with a tough first match against title contender Alexander Zverev.

Another beloved player set to say goodbye is Andy Murray.

Like Nadal, the 37-year-old Briton plans to retire this season and has marked a return to Paris, where he was runner-up in 2016, before stopping.

Murray's plans were almost derailed when he ruptured ankle ligaments in March, but he returned to the court last week after opting against surgery.

Can Djokovic Rebound After a Rocky Season?

Before this year's Australian Open, many expected Djokovic to continue his dominance from 2023 into the new season.

The 37-year-old Serb reached the semi-finals in Melbourne but fell short of his usual high standards.

Since losing to eventual champion Jannik Sinner, Djokovic has faced a turbulent few months in his career.

Coach Goran Ivanisevic and fitness trainer Marco Panichi, long-time members of his team, left after his early exit at Indian Wells.

Djokovic reached the semi-finals in Monte Carlo, losing to last year's Roland Garros finalist Casper Ruud. However, his uncertainty resurfaced at the Italian Open.
