Birmingham City manager Alex McLeish refused to reveal whether the club had made an approach for Sunderland striker Kenwyne Jones.
The Blues are said to have made an £11million approach for the Trinidad & Tobago international but McLeish would not be drawn on the matter.
City have reined in their interest for Celtic midfielder Aiden McGeady and Liverpool striker Ryan Babel though, after being told the pair were not for sale by their respective clubs.
McLeish's side are unbeaten in 12 matches and have enjoyed a barnstorming run of form that has seen them rise to eighth in the Premier League table.
But his charges have netted just 20 times in as many matches - heightening speculation the manager was ready to launch a bid for Jones in an attempt to increase the flow of goals.
"We've made enquiries about a lot of people," McLeish said. "I don't want to confirm or deny a bid has gone in (for Kenwyne Jones).
"There is a lot of transfer speculation now and it is not something I like to talk about when nothing has been done. We have made enquiries for several players. I am not going to confirm or deny any names.
"But as regards Aiden McGeady, we made an enquiry but we were told he is not for sale. The situation won't change until someone says he is up for sale. Is there any movement with the Babel situation? No, we've been told he is not for sale."
One player that could be joining the St Andrews outfit is Giles Barnes, who is without a club following his release by Championship side Derby earlier in the season.
The midfielder has been training with the club and McLeish revealed he will hold talks with the player to decide whether his interest will be pursued further.
He added: "Giles is still training with us. We haven't seen him yet in a game. We are going to speak to him tomorrow and see what he is going to do.
"I believe other clubs are interested in having a look at him but we will speak to him tomorrow and see what he wants to do. He is a good player, has got a good idea about the game, a bit of vision."
