Danny Wilson doesn't expect any imminent additions to his squad, despite watching four trialists play for United's U21s at the beginning of the week.
Greek international and Euro 2004 winner Angelos Charisteas was one of the quartet, but Wilson insists signings are unlikely at the present time.
On Conor Clifford, Craig Lynch and Ted Cribley, who also featured for the U21s, he commented: "We will keep looking at the lads currently with the club, but there are no offers on the table at this juncture.
"We will monitor their progress and see if they are right for us as time progresses, but that won't be in the next week or so."
Speaking about the scorer of Greece's goal in the Euro 2004 final against Portugal, Wilson added:
"We were asked if we would take Angelos (Charisteas), we are fully aware of his background and pedigree, but also we know he hasn't played for a while.
"Of course we want to see what he is capable of and whether or not he is an improvement on what we already have at our disposal.
"It isn't likely he would compete with say Dave (Kitson) at this stage so we need to balance all the options available to us and most importantly any addition must improve the squad."
