Had the same issue with my older DD when she was 3. She clearly had a lot of natural talent, but the minute we tried to put her in a structured setting, she would shut it down and get hostile.
We backed off on the formal stuff but would nonchalantly bring a ball to the park. Sometimes she'd take it and go dribble all over, and sometimes she wouldn't touch it.
When we started her back in a league around 5, I really focused on making sure she associated it with having fun - I'd toss her in the air after practice, have a special treat after games, etc. Now, she loves it - and is a complete and total baller! (Humble brag: She is awesome!!)
Her younger sister (just turned 3), has more interest - obviously because her older sister is doing it - but she still can't handle more than 10 minutes of structured soccer. And now I know that that's fine. Pushing her to the point that she resents soccer is a way bigger risk to her development than taking it easy for a bit while her maturity catches up with her natural skill.
