Novak Djokovic is more than a decade older than any other man in the Wimbledon semifinals. He says it motivates him to see if he can keep going toe-to-toe against the younger players at the top of tennis these days.

The Serbian legend has played excellent tennis up to this point in the tournament and has reacted like a true champion to all the difficulties – especially in the matches against Alex de Minaur and Flavio Cobolli – but he is aware that he will literally have to climb a mountain on Friday.

Every other day at Wimbledon has brought an opportunity to compare the greatest player in men's tennis and one of his heirs.
