Town boss Roy Keane says the Blues have had an offer accepted for a player and could have as many as three new additions to the squad, one a loanee, in time for the friendly against West Ham a week on Saturday. So far, the only signing of the summer is youngster Conor Hourihane, who joined from Sunderland last week.
Keane told the club site: "I was hoping that we could have got a couple of players in earlier but things take time in football and I've not been too worried about it.
"We are making progress now though, and we've had one offer accepted for a player this morning, so I've got to try and finalise things with that.
"We are close on that deal and with another player, which will be a year-long loan.
"There could also be movement with another player coming in as well, so I'll be talking to two or three players over the next few days.
"The players concerned include two that I had in mind at the end of last season. I had a target list of four or five players and, while you rarely get all five, if I get two out of the five I will be pleased.
"Until the players are here and have signed though, there is nothing to get excited about."
The permanent signing may be Sunderland keeper Márton Fülöp, who Black Cats boss Steve Bruce, presumably speaking yesterday, has confirmed was the subject of a Town enquiry.
The Blues and Cardiff have been unable to agree a fee for striker Michael Chopra, although the Bluebirds may ultimately have decided to accept an offer for the former Sunderland striker given their ongoing financial problems and the frontman's outburst regarding their current situation. Cardiff central defender Gábor Gyepes has also been linked in recent days.
Possible loan signings mooted this summer include Tottenham winger Andros Townsend. The second permanent signing Keane mentions could potentially be free agent Steve Finnan, who was linked last week.
