Team GB vs Chile team news
Both squads have no reported injuries before the game.
Team GB have only had one warm-up fixture, so Riise’s lineup is tough to predict.
It will be heavily based on England players, so expect Fran Kirby, named the WSL Player of the Year, and Lucy Bronze, the Fifa Best player in 2020, to both be involved.

Team GB 2-0 Chile.
