LONDON — Before Vivianne Miedema’s brother could walk, she said, she would place him in front of a soccer net and fire shots at the goal for practice.

“He would just stand there; he couldn’t really do anything,” Miedema said with a mischievous smile, shrugging her shoulders. “I was using him, kind of.”

Years later, Miedema is still scoring with ease. Thirty-nine goals in a Dutch league season when she was 18. Six in a single game for the English club Arsenal. And 61 for her country — a record for Dutch men and women.

She has won league titles in Germany and England, and a European one with the Netherlands. In July, she will rejoin her national team when it plays in the Tokyo Olympics. And Miedema is still only 23.
