Celtic manager Gordon Strachan insists he has had no bids for any of his players during the January transfer window.
The Scot's comments come after reports linked Newcastle with a £4million swoop for his captain Stephen McManus.
Reports in Scotland claimed the Magpies even tried to snap up the defender on a loan deal until the end of the season.
Newcastle's interest in the player was believed to have been sparked when the former Southampton boss enquired about taking Toon full-back Jose Enrique on loan.
Dennis Wise, director of football at St James Park, was said to be keen on any deal as long as McManus was involved in return.
This request was answered with a swift rebuttal from Strachan. The former Scotland international failed to name names but did admit that he had received an enquiry for one of his players.
"We have had no bids for anybody. None whatsoever," he told the Daily Record.
"We had an enquiry when I asked someone in England about a loan and they asked about one of our players on loan. I said no. I can't tell you who it was with.
"We have not had any bid whatsoever. The loan thing has not gone through. I asked for one of their players on loan, they asked for one of our players on loan and it was a quick no."
The Hoops are thought to have spoken with Championship side Cardiff over a possible £500,000 deal for midfielder Willo Flood.
The former Manchester City youngster is currently on loan at Dundee United, who Celtic face in a Co-operative Insurance Cup semi-final on Wednesday.
But the 51-year-old boss refused to be drawn on the subject, instead voicing his frustration at having to continually search for bargains in order to bring players in.
"It's not only me. The players are frustrated because they want to play with great players," he added.
"The fans want to see great players, we want to sign great players, you want to watch great players.
"But that's the market we have to deal with. Nobody has bids for any of our players so they can't be that great.
"I like the squad I have here, they are a great squad to work with, but one request to swap someone on loan is all we've had.
"We can't speak about players who are not here. That's only fair, only right. We have enquired about one or two, things are ticking over and we enquired about one on loan last week.
"The market is dead. If you go to England the market is just horrendous so we can't even get involved in that."
