Simona Halep takes on Elina Svitolina

American superstar Serena Williams is tantalisingly close to equalling Margaret Court’s record haul of 24 Grand Slam titles but it’s far from a certainty given her shaky displays so far at Wimbledon.

The 37-year-old seven-time champion had to draw on all her strength -- physical and mental -- to get past unseeded compatriot Alison Riske in the last eight and faces another grass court loving opponent in Barbora Strycova in Thursday’s semi-finals.

The 33-year-old Czech veteran -- the oldest player to play in a woman’s semi-final for the first time -- has found the thought of retirement a spur for playing some of her finest tennis and says she will step onto Centre Court “without any fear”.

The other semi-final pits two seeds against each other, seventh seed and former world number one Simona Halep against eighth seeded Ukrainian Elina Svitolina.

It says a lot about the turbulence of women’s tennis that Serena is making her 12th semi-final appearance while of the other three only Halep has gone this far before, and that was back in 2014.

Serena is the colossus that still bestrides women’s tennis, but there are chinks in her armour as have been exposed both at Wimbledon and in her last two Grand Slam finals.

Outplayed by Angelique Kerber in last year’s Wimbledon final and then a spectacular meltdown in the US Open defeat by Naomi Osaka gives Strycova genuine hope of an upset.

“I don’t know where I am. I do know I feel good.”

However, she has still looked vulnerable and Strycova’s speed round the court and array of shots will pay dividends if she reproduces the leaden-footed performance she put up against Riske.

“She’s good on the grass,” Serena said of about her opponent.

“She knows what to do. She has a good all-around game. She’s incredibly tricky. It’s definitely not easy. “But it’s something I’m definitely geared up for.”

Strycova for her part described Serena as a great champion and amazing athlete but if that indicated she was intimidated think again.

“I don’t have fear,”

“I don’t have such a power like Serena, but I have other weapons. “I will try to use them as much as I can. I will enjoy.

“I have really at this point nothing to lose.”

Halep should prevail in the other clash, not only because of her greater experience and having won a Slam in last year’s French Open, but she says she has at last taken to grass after not being best suited to it when she lost to Eugenie Bouchard in the 2014 semi-final.

Halep showed this in impressing in her previous two matches dealing with the partisan crowd in beating Coco Gauff and then coming back from 4-1 down and break points in the first set against Zhang Shuai in her quarter-final.
