The fee that the Thorns are set to pay is believed to be a league-record, nearing $316,000 (£250,000). The report adds that Fleming said goodbye to all her Chelsea teammates earlier this week, and that she's left the club in good standing.
After the Thorns lost USWNT star Crystal Dunn to free agency earlier this year, it was expected they would be active in the market for a replacement, but bringing in Fleming is a blockbuster move. The 25-year-old will instantly slot into the XI in what would be expected to be an attacking midfield role. Head coach Mike Norris will look to integrate her as fast as possible, with the upcoming season less than two months away.
