"I'm thinking of something that may make you go bananas" - Serena Williams teases fans with latest social media post

Serena Williams took to Instagram on Friday to post a cryptic message that has driven her fans crazy with speculation. The 23-time Grand Slam champion has not played a match of competitive tennis since last year's Wimbledon Championships, where she sustained a leg injury during her opener against Aliaksandra Sasnovich.

With her loyal fans eagerly awaiting news on when they could finally see her in action again, the American teased them with her latest message, saying that something huge was on the cards.

"I’m thinking of something that may make you go bananas, stay tuned!" Williams wrote on Instagram.

Within moments, the comments section was flooded with messages from her followers wondering if her post was tennis-related. The most common assumption from users on Instagram was that she had accepted a wildcard for the upcoming Wimbledon Championships, although it could just as easily be something else.

The official list of players who have been granted a wildcard for the tournament hasn't been announced yet, and it remains to be seen whether it is really the big news Williams was hinting at.

Wimbledon's latest promo features Serena Williams

Amid rumors that Serena Williams could be granted a wildcard for the 2022 Wimbledon Championships, the tournament released an animated promo, which features the American.

In a video released last week by the event's official social media handles, the former World No. 1 took centre stage, along with other stars like Rafael Nadal, Novak Djokovic and Roger Federer.

The commercial was released to commemorate the iconic Centre Court at SW19 completing 100 years in its current location.

The 40-year-old is a seven-time winner at Wimbledon, having triumphed in the 2002, 2003, 2009, 2010, 2012, 2015 and 2016 editions. The American has also reached four further finals at the tournament (2004, 2008, 2018 and 2019).

The 23-time Grand Slam champion has a 98-13 overall win/loss record at the grasscourt Major across 20 appearances.

Furthermore, Serena Williams has also won the women's doubles event on six occasions (2000, 2002, 2008, 2009, 2012 and 2016), partnering her sister Venus Williams.

In mixed doubles, the former World No. 1 has one title at Wimbledon, winning the 1998 edition alongside Max Mirnyi.
