Former Sheffield United striker Billy Sharp is set to sign for Hull City.
Sharp is a free agent after leaving LA Galaxy at the end of the MLS season.
Hull chairman Acun Ilicali said: "Of course the transfer window is very important and we are very focused to bring two or three more players to the club that will make us happy.
"One's already done and unfortunately it's secret but very soon you will learn about him. I can say he was one of our targets and we are very happy to get him. We will get two or three more. We are dying to get to the play-offs and I hope God lets us.
"I want all the fans to know we are working like crazy with the [recruitment] team, sometimes two or three-hour conversations with our coach and our recruitment team. I'm involved in most of them because I'm the one who's going to pay the money so they have to convince me too."
