Natalia Arroyo says Aston Villa will "probably have some updates" before Tuesday's transfer window deadline.
So far, Villa have made two signings with midfielder Oriane Jean-Francois arriving from Chelsea and defender Jenna Nighswonger joining on loan from Arsenal.
Full-back Sarah Mayling left on loan to Leicester City, while winger Katie Robinson joined Bristol City.
"We always need to wait until the last minute to see what can happen. We were quite productive at the beginning and knew what we needed," said Arroyo.
"We will try to make the best decisions, but I'm happy so far with how calm we are in our planning. We are not just thinking of the short-term.
"If we have injuries or whatever, we are not doing things in a desperate mode. We are being smart and have a clear plan of what we're building to be better.
"Let's see what happens but we'll probably have some updates before the end."
Villa travel to Goodison Park on Sunday to face Everton in their next Women's Super League match.
The two teams drew 3-3 in a dramatic encounter in the reverse fixture in November but Arroyo could be boosted by the return of some injured players.
"In the last two weeks we have had players out but we now have good news as Chasity Grant and Gabi Nunes are training with us," she added.
"We will see [in training on Friday] and on Saturday how much they can help us this weekend.
"We are likely to still be without Lucia Kendall, Rachel Maltby, Paula Tomas and probably not Missy Bo Kearns too."
