Gordon Strachan has confirmed that Celtic have made contact with Lukasz Zaluska, although he expects the goalkeeper to stay at Dundee United until the end of the season.
Zaluska recently rejected the offer of a new deal at Tannadice and admitted that he could make the move to Celtic.
The Polish shot-stopper will be out of contract in the summer and Strachan has expressed an interest in bringing him in.
However, the Celtic boss has refused to say whether Zaluska is being viewed as a replacement or a back-up to compatriot Artur Boruc.
"He will be Dundee United's player until the end of the season, I would imagine," said Strachan.
"We have had contact with the player, we are allowed to do that.
"Where it goes from there, I don't know."
Celtic have also been linked with a swoop for West Ham striker Craig Bellamy, although the Welshman this week played down transfer talk by claiming the Bhoys could not afford to pay his wages.
Strachan has worked with Bellamy in the past but he concedes he will not be able to sign him.
"I looked at a website to see what he was saying and I agree with him," Strachan explained.
"He was talking about his wages and transfer fee.
"I am huge fan of Craig Bellamy, I bought him (for Coventry), but I agree with what he says, it would be near impossible.
"It's a nice dream but I don't think that will happen."
