Lucy Loomes has joined the club after a completing the Women's Super League 2 season with London Bees.
The striker, 18, has represented England at Under-17 and Under-19 levels and was part of the Lionesses' squad last time out for a 1-1 draw in Italy on November 4. That was preparation for the Euro qualifiers next year when England take on Sweden, Austria and Belgium for a place in the finals in Slovenia in July.
"This is a massive boost for the club," said manager Karen Hills, who now has three international players in the squad as Lucy joins Avilla Bergin (Northern Ireland) and Megan Wynne (Wales).
"Lucy is absolutely clinical in front of goal with a fantastic work rate and she'll give us that additional bite in forward areas that we'll need in the next four to six weeks."
SPURS LADIES 0-4 POMPEY - SUNDAY, NOVEMBER 22
Spurs were blown out of the water by Portsmouth in the first half as they suffered a real jolt in the FA Women's Premier League on Sunday.
Karen Hills described it as a 'shock to the system' and a 'one-off performance' as her team slipped to an early 1-0 deficit and then trailed 3-0 at half-time before the final 4-0 scoreline.
It might have been a different story but for two key moments in the first half. Megan Wynne was denied one-on-one by Pompey goalkeeper Courtney Trodd at 0-0 and then with the score at 2-0, Trodd denied Jenna Schillaci from the penalty spot after Wendy Martin was fouled and Wynne struck the rebound against the post.
Ini Umotong made it 3-0 before half-time and after an even second half, Umotong added a late fourth.
"They started quicker than us all over the park, caught us sleeping early for 1-0 and we just couldn't recover," said Karen. "We couldn't deal with the threat of their front two and got punished.
"We were all devastated especially after we'd worked so hard to beat West Ham last week. I really don't know where the performance came from, it all just unravelled for us.
"It was a game to forget but we've got to snap out of that quickly as we now play Gillingham on Wednesday."
Spurs Ladies v Pompey: Toni-Anne Wayne, Sophie McLean (Rosie Kmita 75), Alex Keown, Jenna Schillaci, Leah Rawle, Shannon Moloney, Maya Vio (Avilla Bergin 60), Wendy Martin, Kelley Blanchflower (Katie O'Leary 53), Megan Wynne, Bianca Baptiste. Substitute (unused): Lucia Leon.
GILLINGHAM v SPURS - RYMAN CUP QF - WEDNESDAY, NOVEMBER 25
Spurs Ladies travel to Chatham Town FC to take on Gillingham of the FAWPL South East Division One tomorrow night (7.45pm).
"We've got to put Sunday behind us, go back to basics and we'll be okay," added Karen.
