Serena Williams teases fans with potential retirement U-turn: "I'm a little bored"

Serena Williams has teased fans about a potential return to tennis by posting a photo of racquets with the caption 'I'm a little bored'.

Williams always avoided using the word 'retirement' preferring to call the process 'evolving'. She teased a potential return a couple of times even going so far as to claim she's not retired with another tease coming recently.

She was spotted practising with her sister Venus but she also posted a photo on social media with the caption 'I'm a little bored.'

It's unclear whether she will make a return in Australia but there is a chance.
