Brendan Rodgers revealed Celtic once came close to signing Declan Rice as he highlighted the precarious nature of January transfer deals.
Rodgers hopes to add to his squad early in the month but added a note of caution in the tale of England midfielder Rice, who moved from West Ham to Arsenal in a £105million deal in the summer.
Rodgers has previously spoken of the need to sign players who can make an instant impact with most of the club’s summer signings still to establish themselves in the team.
The Celtic manager, whose first spell in Glasgow came in 2016-2019, said: “The club will do absolutely everything we can to support what we need and what the team needs.
“There is lots of work going on in the background, and I’m pretty sure that in this early period of the month, we can have some joy and get one or two in. Ideally you’d want to get them in (early).
“Deals can be complicated and things that might have been there for three or four months can fall away. That’s always the challenge – it only takes one injury to (affect) a player who was lined up to come in.
“I remember when I was here the first time, we spent about three months looking for Declan Rice to come in.
“Declan was all set to come in and then all of a sudden they (West Ham) had an injury, he stayed and got in the team and the rest is history. That’s not the club’s fault – it’s just the way it goes.
“We have a number of positions we want to prioritise. There are other positions where we won’t be able to do anything until the summer, I know that. But what I do know is that we want to improve the squad and the club are very happy to support that.”
Rodgers is looking to reduce the size of his squad this month but that process is subject to external influences as well.
“I have regular dialogue with players but still we obviously have to wait and see as well because some players may want to go out but, if we don’t get the players in that we need, then I have to ensure the squad is as strong as it possibly can be for the second part of the season,” he said.
