Five top contenders for the men's singles title at the French Open, which starts on Sunday.

CARLOS ALCARAZ (SPAIN)

At the outset of the 2022 French Open, Carlos Alcaraz was everyone's favourite up-and-comer, dripping with potential and touted for greatness.

A year later, the Spaniard has surpassed all expectations, having won his maiden Grand Slam title at the U.S. Open and bagging back-to-back claycourt titles in Barcelona and Madrid in recent weeks.

The 20-year-old suffered a shock exit from the Italian Open at the hands of qualifier Fabian Marozsan earlier this month, after which he spoke of the need for a mental reset, but few would bet against the world number one resuming normal service in Paris.

DANIIL MEDVEDEV (RUSSIA)

Medvedev has always said that clay is his least favourite surface to play on, but the Russian might be tempted to change his mind after claiming his first-ever title on the surface at this month's Italian Open.

In a sign of his marked improvement on clay, the 27-year-old put in a masterful display to clinch a 7-5 7-5 victory over Denmark's Rune in Rome, indicating the former world number one may finally have the tools needed to go all the way in Paris.

"I think we can expect more from him ... all of a sudden, you say, 'wait a minute, he can play on clay, he's actu...
