"She's Muhammad Ali's daughter, she's not Muhammad Ali."
That's boxing superstar Claressa Shields essentially telling Laila Ali to put up or shut up ... after Ali trashed Shields this week as an inferior fighter.
Shields appeared on the "TMZ Sports" TV show (airs weeknights on FS1) to respond to Ali's insults ... and yeah, Shields was FIRED UP!
"Let's just keep it honest. Don't say that I'm not talented because I'm the most talented female fighter there has been in the history of boxing."
Of course, 42-year-old Ali went on "Sway in the Morning" and said she would destroy Shields if they ever fought because Claressa isn't talented enough to hang with her.
