Stoke City assistant manager Dave Kemp has said that the club could sign as many as "four" players before the end of the transfer window.
"There is no guarantee, but it could be any number between zero and four - let's put it that way," said Kemp.
Kemp remained tight-lipped over Adam's situation, however, adding: "I don't really want to discuss particular players, and he is not our player. He is a very good player, but so are lots of other people out there. If he becomes our player, or any other player comes, we can speak about them then."
Kemp also revealed that American international Edu is not far from joining Tony Pulis's side.
"He has been granted the work permit, but as usual, there are other bits of paper that have to be stamped and marked.
"He has another appointment tomorrow, I think with the Border Agency, just to clarify that. But he has been granted the work permit, so hopefully we are very close to getting that over the line." He added.
Stoke travel to Wigan Athletic this weekend.
