Manchester United completed a fourth deadline-day signing on Friday as Melvine Malard joined from Lyon.
The 23-year-old forward, a two-time Champions League winner with the French side, joins on season-long loan.
United also completed the £150,000 signing of Everton defender Gabby George on Thursday.
George’s signing was followed by the arrival of midfielder Irene Guerrero from Atletico Madrid and goalkeeper Phallon Tullis-Joyce from OL Reign.
“I am truly very happy to be here, and to join this club and this city. I cannot wait to meet the fans and get started,” said Malard.
Manager Marc Skinner added: “Melvine’s honours speak for themselves, and we are delighted to welcome a proven winner at domestic and European level to our Manchester United family.”
After her arrival on Thursday, American goalkeeper Tullis-Joyce, 26, said: “Today has been pure excitement for me.
“Manchester United is such an historic club, that has already done so much in the women’s game. I’m so honoured to get this opportunity.”
Spain midfielder Guerrero, 26, was part of the Spain squad who were crowned champions at this summer’s Women’s World Cup.
“I am very proud to be part of the Manchester United family and look forward to achieving all our goals together,” said Guerrero.
Skinner said: “Irene is a World Cup winner whose quality is an excellent addition to our team.
“The experience she brings, both domestically and internationally, will be key as we pursue success across the multiple competitions.”
Later on Thursday, United defender Jess Simpson, 18, completed a season-long loan move to Bristol City after signing a first professional contract in January.
On Friday, 19-year-old forward Alyssa Aherne also left the club to join Everton on a season-long loan.
