There appears to be no stopping Serena Williams after she again beat Maria Sharapova to stand on the brink of another Wimbledon title.
Maria Sharapova had no answer to the phenomenal Serena Williams once again as the world number one's dominance of her big rival continued at Wimbledon on Thursday.
It is 11 years since Sharapova sprung a surprise by beating Williams to win her only Wimbledon final at the age of 17.
The Russian got the better of the 20-time grand slam champion again later that year, but since then Williams has reeled off 17 consecutive victories against an opponent it is no secret she does not see eye-to-eye with.
An imperious Williams has lost only one set against Sharapova in seven years after winning 6-2 6-4 to reach yet another final at the All England Club.
The 33-year-old, who will be expected to beat Spaniard Garbine Muguruza on Saturday, took advantage of a below-par display from the Russian to triumph on Centre Court.
She also beat Sharapova in the Australian Open final in January, as well as coming out on top when the two last locked horns at SW19 in the 2012 Olympic Games final.
There is no sign that Sharapova will be able to end her long losing streak against her old adversary in the near future as Williams attempts to make history.
While Sharapova must reflect on another defeat to the outstanding American, Williams remains on course to claim a first calendar Grand Slam - and it would take a brave punter to back against her.
Her power, precision and sheer determination to succeed will surely see her go down as the greatest female tennis player in the history of the game and she will attempt to win a sixth Wimbledon title this weekend.
Not only that, she would also complete a second 'Serena Slam' - holding all four grand slam titles - if she beats surprise package Muguruza.
And she would also then head into the US Open knowing a victory would ensure she won all four majors in the same year for the first time.
Muguruza beat top seed Williams in the French Open last year, but gained revenge with a victory en route to winning the Australian Open earlier this year.
The Venezuela-born 21-year-old had never been beyond the second round at Wimbledon before her amazing exploits this year and the 20th seed admitted she has even shocked herself.
Muguruza spoke of realising a dream after beating Agnieszka Radwanska in the semi-finals. Now she will attempt to shatter Williams' own dream on Saturday.
