Rafael Nadal is looking for the third leg of the Grand Slam while Emma Raducanu searches for form after run of injuries
The last time that none of Roger Federer, Rafael Nadal, Novak Djokovic or Andy Murray occupied either of the top two ranking spots, its current inhabitants were seven and six years old respectively.
It would have been reasonable to assume that such a scenario would suggest a significant change at the top of the sport but Djokovic and Nadal are the main protagonists at Wimbledon for another year. Despite where they sit in the rankings, they are somehow also the top two seeds in the absence of a banned Daniil Medvedev, the world No 1, and an injured Alexander Zverev.
