Celtic boss Neil Lennon has confirmed the signing of striker Pawel Brozek from Trabzonspor subject to a medical.
Rangers manager Ally McCoist was interested in the forward but their Old Firm rivals have agreed terms with the player.
Subject to a medical, he will sign on loan until the end of the season, with a permanent deal on the table.
Celtic boss Lennon confirmed the capture after Anthony Stokes scored twice in the Hoops' 3-1 League Cup semi-final win over Falkirk to set up a final meeting with Kilmarnock.
"I know Rangers were interested but we have been involved with players before and Rangers have nipped in," said Lennon.
"I am not saying we have nipped in but we have been tracking him for quite a while. We have tried to keep it under the radar.
"I have not seen him yet but if he does come in I will be delighted.
"We will see how he is and if he is ready to go he won't be far away from starting. He scored a lot of goals in Poland and he will give the squad a jag.
"We can't keep relying on Gary Hooper and Stokesy for the goals.
"If one of them gets injured or suspended, we could be a goalscorer short and Pawel is a goalscorer.
"He has gone to Trabzonspor and for one reason or another it has not worked out but what we do know is he is a goalscorer.
"He is a bit like Hooper, he knows where the goal is. We might try to get another player in before the window closes, we are always looking."
