20-year-old USWNT winger agrees five-year contract

Chelsea have until 11pm BST to complete club-record deal

Chelsea are on the verge of signing the United States winger Alyssa Thompson from Angel City on the Women’s Super League’s transfer deadline day, for an upfront fee understood to be just shy of $1.5m (£1.1m), which sources say could climb close to a world-record sum with potential add-ons.

The 20-year-old completed a medical on Thursday in London, after boarding a flight from Los Angeles late on Wednesday night, amid extensive negotiations between the two clubs. All parties are increasingly confident the move will be finalised in time for the 11pm BST transfer deadline.

The current world record transfer fee for a women’s footballer stands at the $1.5m that was paid by Orlando Pride last month to sign Lizbeth Ovalle from the Mexican side Tigres, which eclipsed the £1m move by Arsenal to sign Olivia Smith from Liverpool in July. It is understood Chelsea’s move for thompson would not be a world-record fee upfront but could rise to be so with add-ons.
