Now the club’s chief Ivan Kmotrik has urged the Scottish giants to make their move quickly or they could lose out on the forward.
Kmotrik confirmed a meeting with Celtic roughly two weeks ago and he also revealed that he is still waiting for an official proposal from the Scottish outfit.
Speaking to Daily Record, he said: “On December 23, there was a meeting between SK Slovan Bratislava and Celtic in the presence of Sporar’s agent. We discussed with Celtic the possibilities for a potential transfer. Celtic responded that they would send an official proposal.
