Ronny Deila says there is little chance of Aiden McGeady re-signing for Celtic.
The Bhoys are expected to be active in the January transfer window, just as they were a year ago with the signings of Gary Mackay-Steven and Stuart Armstrong, both from Dundee United.
Now, with Celtic out of the Champions League and the Europa League, under-pressure manager Deila has to bring in new faces to make sure that he wins the Scottish Premiership title.
Celtic sit level on points with Aberdeen at the top of the table, but they do have two games in hand on the Dons, meaning they are still favourites to clinch the title for a fifth straight season.
One player who fans have been wanting to see the club sign is Aiden McGeady, who is currently out of favour at Premier League club Everton.
The 29-year-old winger, who joined Celtic from Queen's Park at the age of just 15, went on to make 252 appearances for the Bhoys, racking up 37 goals and 83 assists before leaving for Spartak Moscow in 2010.
Now a forgotten man at Everton, the Republic of Ireland international needs first team football ahead of Euro 2016 - and some Celtic supporters want him to return to Glasgow and thrive once again.
However, manager Deila has been asked about a possible return for McGeady, but told The Herald that a deal is virtually impossible unless the winger drops his wage demands - and would want the player permanently, not just on loan.
"We have tried before to get those types of players but they get three times the salary at other places," said Deila. "It’s also more interesting for them to play in England than Scotland. It’s tough and you never say never but it’s a different planet when you talk salaries. We would not be able to pay the salary that the likes of McGeady are on. The difference is so unbelievably big that’s there is no chance. The wage structure would be broken 10 times if we did that!"
"Maybe with players like McGeady, who has been here before, when he reaches the end of his career he’ll want to come back again. That’s possible, of course. But I haven’t talked with him about that, although these types of names we are talking about. I don’t know what Dermot did before. You’d need to talk with him about that. But we’d need to have the opportunity to buy him. That’s an important thing for us," he added.
