At the same time, bonuses in the contract can make her the most expensive in the world – close to five million kroner, reports Sky Sports.
Mayra Ramirez, who scored five goals this year for Levante in the Spanish league, has signed a four-and-a-half-year contract with the London club.
The previous transfer record in women’s football was when Kiera Walsh left Manchester City for Barcelona for a reported fee close to £4.3 million.
Ramirez thus joins the Swedes Johanna Rytting Karneryd, Zecira Musovic and Nathalie Björn. Chelsea lead the Women’s Super League by three points ahead of Manchester City.
