It was only last year that Kerolin actually signed for Man City, arriving in the 2025 January transfer window after three years in the United States with the North Carolina Courage. She showed glimpses of her talent in those first few months at the club, scoring four goals before the season's end,then exploded into life in her first full campaign in the Women's Super League.
In 2025-26, Kerolin scored nine goals and provided five assists in the WSLas Man City won the title for the first time in 10 years, with her hat-trick in the 5-1 thrashing of then-holders Chelsea in February a stand-out performance. The 26-year-old's 14 direct goal contributions was only bettered by three players in the division - City stars Khadija Shaw and Vivianne Miedema, and Arsenal striker Alessia Russo.
Those numbers came despite Kerolin only starting nine league games, too. The forward picked up an injury early in the campaign which ruled her out for almost three months, and once she returned to fitness, competition for places was tough, especially with the team having started the year so brilliantly. Her ability to make an impact from the bench saw her force her way in the line-up quickly, though, and a run of seven league starts in the title run-in would return seven goals and two assists to put City on the brink of triumph.
