10:00 CET - Good morning and welcome to our coverage of today’s tennis at the Madrid Open, as the men's quarter-finals get underway and the remaining two women's last-eight ties also take place.
Play gets started in a few hours at 13:00 CET, with experienced Czech Karolina Pliskova coming up against lucky loser Anastasia Potapova, who claimed the scalp of second seed Elena Rybakina in the previous round.
Following that clash, the first of the men's quarter-finals sees top seed and heavy favourite for the title, Jannik Sinner, take on rising star Rafael Jodar in a highly-anticipated match-up.
The Italian is looking to extend his 20-match winning streak and move a step closer to claiming a fifth straight Masters crown, while 19-year-old Jodar will be hoping to continue his remarkable recent form in his first real test against elite opposition.
Later on in the evening session, the final women's quarter-final sees 13th seed Linda Noskova face Ukraine's Marta Kostyuk, who is on a nine-match winning streak on clay after securing the WTA 250 title in Rouen earlier in the month.
Finally, talented Frenchman Arthur Fils comes up against Jiri Lehecka in a fifth career meeting between the pair, with the head-to-head currently tied at 2-2.
