Ipswich boss Jim Magilton wants to sign former Town defender Titus Bramble and Crewe midfielder David Vaughan.
Bramble could return to former club Ipswich
Bramble, 25, who joined Newcastle from the Suffolk club in 2002, will not be given a new Magpies contract when his deal expires at the end of the season.
Magilton told the East Anglian Daily Times: "If there was a possibility of signing Titus I would do it right now."
Meanwhile, Magilton has confirmed he is interested in Crewe's left-sided player Vaughan, 23, and has had him watched.
Magilton added: "We've not asked about Titus yet but if he is available and would like to come, then we will be in there finding out."
"David is someone I like and we have watched but Crewe are not interested in doing a deal just yet.
"That may change but we now have Gary Roberts and he can do a similar job."
