Chelsea signed United States defender Naomi Girma from San Diego Wave in a reported world-record deal for a female footballer.

girma is believed to have cost Chelsea 900,000 euros ($1.1m), surpassing the world record of 685,000 euros ($718,976) paid by Bay FC for Racheal Kundananji in February 2024.

The 24-year-old was unveiled on the pitch by the Women’s Super League champions before Sunday’s game against Arsenal at Stamford Bridge.

“I’m so happy and really excited to be here. It doesn’t feel real,” Girma told Chelsea’s website.

“There are a lot of things about Chelsea that made me want to come here, the culture, the winning mentality, staff and players. It’s a top environment to learn and grow in.”

Girma becomes Chelsea Women’s boss Sonia Bompastor’s first signing of the January transfer window.

She was targeted by Bompastor after Chelsea defender Kadeisha Buchanan suffered an anterior cruciate ligament injury that could rule her out for the rest of the season.

The fee eclipses the previous British record set when Chelsea signed striker Mayra Ramirez from Levante for 384,000 euros ($403,046) a year ago.

Girma played every minute of the US’s victorious Olympic campaign in Paris last year and was also named US Soccer’s female player of the year in 2023.

Chelsea head of women’s football Paul Green said: “Naomi is a world-class defender who is now coming into the prime years of her career.” (Al-Jazeera)
