Serena Williams may have retired from tennis but is starting another role.

She unexpectedly became a coach at her daughter Olympia's soccer game.

The pro posted this video on her Instagram explaining how she got a new role.

She initially went to the game to chill but left looking drenched in sweat.

Her father also posted a picture on his Instagram featuring the pair at the same age, dressed in almost identical soccer gear.

The toddler made waves in the world of sports when she became the youngest owner of any professional sports team.

She earned stripes showing off her football skills alongside "Angel City F.C." players.

The tennis star took over the fashion world during "NYFW" alongside her five-year-old baby girl.

The toddler was the highlight of the video montage her mother posted showing behind the scenes of her runway show.
