Luvanga has been prolific in the Saudi league and now heads to the United States Tanzanian striker Clara Luvanga has joined the Washington Spirit from Saudi Arabian club Al-Nassr in a deal believed to be one of the most costly in the history of women's football.
The fee paid by the National Women's Soccer League side has not been officially disclosed. Some are reporting it to be $2.3m , external (about £1.7m), which would make Luvanga the most expensive female footballer in history.
BBC Sport has not been able to verify this figure, although a well-placed source said they believed it ranked in the top five most expensive signings in the women's game.
The Spirit declined to comment on the fee involved when contacted by BBC Sport. Luvanga, 21, has signed a contract running to the end of the 2029 NWSL season.
If the reported record figure is correct, it would mean the fee passes the £1.4m that London City Lionesses are said to have paid to Paris St-Germain for Grace Geyoro last year.
However, the Geyoro fee has been disputed, further illustrating how transfer figures in the women's game are often kept private. With her move, Luvanga becomes the first Tanzanian player in NWSL history.
