The ATP Tour calendar currently has a heavy focus on clay, with the various events building up towards the French Open.
Casper Ruud is being tipped to win the French Open this year, but he is first eyeing success at the Madrid Open this week.
Carlos Alcaraz is capable of shining on clay in the absence of Rafael Nadal, although worryingly he was forced to withdraw from Madrid due to injury.
Nadal once dominated the clay courts, having won a record 14 French Open titles, with Alcaraz now aiming to take over from his idol.
Novak Djokovic meanwhile is still chasing an elusive 25th Grand Slam title on the ATP Tour, but his current form means that is unlikely to arrive at Roland Garros.

His fellow legends Nadal and Roger Federer have already retired, while the likes of young stars Alcaraz and Jannik Sinner have been enjoying huge success in recent seasons.

But it seems that fans must now accept that the past is the past and the new generation have officially arrived, without even mentioning future superstars Joao Fonseca, Jakub Mensik, Learner Tien and Alex Michelsen among others.
