we’re definitely not happy with the situation,Serena Williams’ coach Patrick Mouratoglou told CNN’

With warmup tournaments coming to a close, attention now turns to the main draw of the Australian Open, the buildup to which has been dominated by coronavirus precautions.

A positive test for a hotel quarantine worker earlier this week caused play to be suspended and forced between 500 and 600 players, officials and support staff into isolation.

Every player has since tested negative for the virus.

When the Australian Open does get underway on Monday, two players will have a shot at history: Serena Williams will continue her pursuit to equal Margaret Court’s record of 24 grand slam titles, while Rafael Nadal could surpass Federer’s tally of 20.

Neither has enjoyed a smooth run-in to the first grand slam of the year.

Nadal withdrew from the ATP Cup earlier this week with a stiff lower back, while Williams was forced out of her Yarra Valley Classic semifinal with a right shoulder injury.

She also admitted that the later start date in Melbourne enabled her recover from an Achilles problem.

Last year was the first time since 2006 that Williams had gone a whole year without reaching a grand slam final.

Since her last major victory at the 2017 Australian Open, she has finished runner-up on four occasions.

“Four years without a grand slam is long, even more for Serena than for a lot of players, and we’re definitely not happy with the situation,” Williams’ coach Patrick Mouratoglou told CNN’s Christina Macfarlane late last year.

“We expected better results, but also the situation was new and I’m here talking about becoming a mother and the consequences of it.

“Physically it has been a struggle to come back. It took time, more time than probably what we expected, mentally too. It’s a new balance that you have to find.”

Williams was pregnant with her daughter Olympia when she won her 23rd and last grand slam title in Melbourne.

According to Mouratoglou, motherhood has allowed Williams to reassess her priorities and he notes that, while she wrestles with injuries, her desire to win burns as strongly as ever.

“Serena’s dream, since she’s a kid, is to win grand slams,” he says.
