Chelsea are closing in on the signing of
San Diego Wave centre-back
Naomi Girma for a world-record fee, sources told ESPN.
The transfer fee would see Girma become the first player to break the $1 million mark in the women's game.
ESPN first reported Chelsea's interest in Girma last week, with
Arsenal and
Lyon also keen to sign the
United States women's national team star. ESPN also reported first that this would likely become the first $1m transfer fee in women's football.
Girma, 24, is understood to have agreed to terms with Chelsea ahead of the move. She was under contract until 2026 with the
NWSL franchise, but Chelsea will pay a record fee to secure her services.
Girma is one of the highest-rated defenders of her generation and was instrumental in helping the USWNT achieve gold at the Paris Olympics, with manager Emma Hayes hailing her as "the best defender I've ever seen."
