Paul Jewell is still hoping to bring former loan star Keith Andrews back to Ipswich, but admits he is unlikely to land Danny Collins.
Both men have taken in productive short-term spells at Portman Road this season, with Andrews' goalscoring exploits catching the eye.
His loan agreement came to an end last weekend and he has since returned to parent club Blackburn.
Jewell is hoping he has not seen the last of the Republic of Ireland international, but admits he faces a battle to bring him back to Suffolk.
"I spoke to Keith's agent on Friday," he said.
"He's got a lot of interest from Premier League sides and the problem is that because it's so early in the window, they probably don't want to dive into the first thing on offer.
"You've seen it before, in the last few days of the window some stuff comes out of left field. We'd like to bring Keith Andrews here, we really would. Keith did really well and he knows that we like him."
While remaining optimistic regarding his chances of bringing Andrews back, Jewell concedes that Stoke defender Collins will probably not be returning.
He added: "I spoke to [Stoke boss] Tony Pulis last week and I think Danny's looking for something local to where he is. His wife's just had a baby and he's settled in that area, so I think his family situation is dictating that. But again, that could change later in the window."
Jewell has also lifted the lid on the contract discussions currently being held at Portman Road, with Grant Leadbitter and Josh Carson among those hoping to land new deals.
"They're ongoing. I think all parties are a little bit embarrassed to be holding contract discussions [at the moment]," said Jewell.
"I said to the players on Sunday that I understand there's a lot of uncertainty around the place because there are a lot of contracts up and we've had a lot of loan players, and there's a lot of talk around the place.
"Let's just try and focus on trying to getting some results. Let's try to group together as one. Everyone's battering us at the minute, let's try and use a bit of a siege mentality."
