The draw pits two major names against each other while the other tie sees two less familiar players face off.

Twentieth seed Garbine Muguruza is up against thirteenth seed Agnieszka Radwanska.

This is the highest ranked Muguruza has ever been and if she reaches the final, she will break the top ten.

Radwanska is the more experienced player with three Wimbledon semi-final appearances in the last four years; and a 2012 final defeat to Serena Williams. After dropping just one set so far at Wimbledon, she is the favourite to make the final.

The second semi-final sees two heavyweights face off in Serena Williams and Maria Sharapova.

It’ll be their twentieth meeting and in the nineteen so far – Williams has won seventeen.

Sharapova has failed to defeat Williams in the last eleven years and if she is to make Saturday’s final, she will have to overcome Williams’ psychological advantage.
