On the women’s side, world No.1 Iga Swiatek is carrying momentum from her title run in Stuttgart last week and will be keen to capture the one big clay title that has eluded her so far.
The 21-year-old Pole missed Madrid last year and has only played it once, in 2021, where she fell to Ashleigh Barty in the round of 16.
Swiatek has lost just twice on clay since that defeat to Barty two years ago and the reigning Roland-Garros champion is undoubtedly the woman to beat this fortnight in the Spanish capital.
She is keeping her expectations in check though.
“Madrid is tricky with the altitude, so I'll see,” Swiatek told WTA Insider.
“I've only played twice at altitude. I may be World No.1 but I don't have as much experience in tennis as you may expect. So I'm just going to see. My coach is a guy with a lot of knowledge. So I'm sure he's going to help me manage that properly and get used to the conditions faster than I did in 2021.”
