The 23-year old Finland international has emerged as a target for the Hoops and Lennon feels his club will still be able to conclude a deal despite Schalke's number one attacker Klaas-Jan Huntelaar sustaining a knee injury that will sideline him for around a month.
"I don't think it will have any bearing on him coming here or not," Lennon told reporters on Monday ahead of Celtic's Champions League qualifier against Shakhter Karagandy.
"We did make the offer before the Huntelaar injury so I imagine that wouldn't have helped things.
"I spoke to John Park (football development manager) late last night and he was working on a few players but no news today.
"I probably won't know until I get back from training tonight."
