After the ladies completed their quarter-final matches yesterday, it is now the men's turn to battle their way to Wimbledon's last four.
Andy Murray's match against the unseeded Vasek Pospisil is scheduled for 1pm on Centre Court. It is the first time Pospisil has reached a Grand Slam quarter-final and Murray is unbeaten in his three matches against the Canadian underdog.
Second on Centre is World No1 Novak Djokovic against ninth seed, Croatia's Marin Cilic.
A deciding fifth set in Djokovic's gruelling fourth round match against Kevin Anderson had to be played off yesterday, but the Serbian has a 12-0 record against Cilic and remains the bookies' favourite to defend his crown and take home his ninth Grand Slam title.
On Court No1 at 1pm Roger Federer is scheduled to face France's Gilles Simon, seeded 12th.
The 33-year-old Federer needs no introduction, but the 17-time Grand Slam winner has nevertheless belied his years to stroll to his 13th Wimbledon quarter-final. Simon's hopes, however, will be bolstered by his surprise straight set victory over sixth seed Tomas Berdych in Monday's fourth round tie.
After Federer and Simon's match is concluded, fourth seed Stan Wawrinka is due on Court No1 for his quarter-final against Frenchman Richard Gasquet, seeded 21st.
Wawrinka is reigning French Open Championship and is the only quarter-finalist yet to have dropped a set all championship. This is the third meeting between the two, with the record currently standing at 1-1.
