Manager Derek McInnes insists he could only bring Leigh Griffiths to St Johnstone on loan if he offloads a couple of his own players.
Reports suggest the Saints boss is interested in signing Griffiths on a short-term deal if the Dundee United forward completes his move to Wolves.
The 20-year-old is set to have a spell training with the Premier League club after they held talks with United chiefs, having bid £150,000 for the youngster.
However, McInnes insists he would need to cut back his current squad before he can even think of adding Griffiths, or anyone else, on loan.
He said: "As much as I would like to bring in one or two players on a loan deal - and I have got targets - it's totally dependent on one or two of our lads finding themselves somewhere else to play.
"Only if that happens will I be able to get something done.
"Leigh Griffiths is a player I have always liked and it's no secret that he's someone I would have liked to bring to the club in the past.
"He's just earned himself a great move to Wolves. It's all right wanting people on loan but it depends on one or two lads going out.
"There are loads of players who I think are good players and who would do well for our club but it's another thing getting them.
"So there is nothing in it at the moment."
