Well, she only needs two more victories and has just stunned tw-time grand slam finalist Karolina Pliskova 6-3, 7-5 to book her place in the final four.

Linette, 30, made the crucial break in the 11th game of the second set and held her nerve to serve out the match.

In her previous 29 grand slam appearances, Linette had never advanced further than the third round.

“It’s so emotional; I can’t really believe it,” she said.

“Dreams come true.

“I don’t want to get too excited because we’re still in the tournament but I’m super grateful and happy.”

All five of Linette’s scalps at Melbourne Park this year have been ranked inside the top 50 and included in-form Frenchwoman Carolina Garcia.

And as an unseeded player she has a real chance of doing something that has only been done twice before in the Open era, win the tournament as an unseeded woman.

Serena did it in 2007 when coming back from injury and a sabbatical from the sport.

Before that Australia’s Chris O’Neil achieved the feat in 1978 and was much more of an upset winner than Williams was.

The loss means Pliskova’s long wait for a maiden grand slam title continues.

The 30-year-old Czech has lost both of her major finals – at the 2016 US Open to Angelique Kerber and at Wimbledon two years ago to Ash Barty.
