Novak Djokovic will be vying to defend his Wimbledon crown this year and is still playing some of his best tennis after all these years so he will be in a good position to do so.
Rafael Nadal will be looking to win Wimbledon this year and keep the hopes of a calendar Grand Slam alive.
Matteo Berrettini was out of action for a few months and it wasn't clear if he would make this list but he won both the Stuttgart and Queen's tournaments on grass after coming back and made this list with flying colors(colours). He was the runner up at Wimbledon last year and will be hoping for a different result this year.
Carlos Alcaraz is the most impressive of the next gen players and has been making waves since last year. We'll have to see how he adapts to grass but he has the game and mindset to win a Grand Slam title.
