Slaven Bilic says he wants one more player to arrive at West Ham United this summer.
The Hammers have recruited well so far, with Pablo Zabaleta, Marko Arnautovic, Joe Hart and Javier Hernandez all arriving at the club.
A deal for Sporting Lisbon midfielder William Carvalho is also being discussed.
"We will see what happens in the last week of the transfer window, if somebody is going to leave or come in," said Bilic.
"Like most clubs we are ready to do something, both ways in case something good comes on our plate.
"I'm happy with the squad now. I would like to have one more and after that, if somebody leaves we have to fill that gap because we don't have a big squad.
"This is our squad for the season, or at least until January. We are happy but if somebody leaves we have to be ready to act."
