Returning superstar Daisy Pearce has described an AFLW premiership as the "missing piece" in her glittering career but insists she won't feel empty if she ends her playing days without a national league flag.

Pearce, 31, is back and raring to go for Melbourne when their campaign begins against North Melbourne on Saturday after giving birth early last year to twins Sylvie and Roy.

The champion midfielder - also back as Dees skipper after missing the 2019 season - said she had questioned her ability to return to the top-level following the births.

"I've definitely had doubts along the way. Whether I'd get myself back, there's a lot about pregnancy and having babies and being a mum that are out of your control, physically, mentally, emotionally," Pearce told The Age at Tuesday's AFLW season launch.
