The Hoops boss cast his eye over Schalke's Finnish international forward Teemu Pukki, pictured, in midweek and, despite the German side saying the 23-year-old is not for sale, he is keen to do a deal to bolster his attacking arsenal.
Lennon can add one new player to his squad before Tuesday's play-off round tie with Karagandy but admits even if a move can be forced through, he will have to go with what he has got for the first leg clash as the champions bid for a lucrative group stage berth. He said: "I'm hoping to [add to the squad before Tuesday] yes. You all know about Pukki.
"We have put a bid in. Schalke have said they're not willing to sell. But these are the barriers you come up against now and again.
"We're working very hard to bring players in. We do like him, we think he's a very intelligent player who can make us better. We're still negotiating.
"He's similar to Gary Hooper. He's got that stocky build, he's maybe not as physical as Gary but his moment is excellent and so is his first touch.
"He's a good finisher. I think he'll suit our style of play.
"No [he won't play on Tuesday], we'd be basically looking at the second leg.
"We'd have no time to get the visa done. We'll be all hands to the pump to get him in - or we do have other options as well.
"I've seen him in the flesh now a couple of times. He's an impressive player but he's not getting much football at Schalke which might work in our benefit."
While Lennon is eager to add to his ranks in the coming days, he has quashed speculation surrounding the future of keeper Fraser Forster.
The Englishman was this week linked with a £5million move to Portuguese giants Benfica but Lennon, who has already lost star men Victor Wanyama and Gary Hooper in big- money deals this summer, insists his No.1 is going nowhere.
He said: "It's a rumour that's spread in the last few days. I don't know if they're trying to unsettle the player.
"There has been no concrete enquiry for him. He's not for sale. There's no way I'd let him go. It doesn't surprise me but he's not for sale."
