The prolific striker played 25 minutes as the Hoops beat Cliftonville 2-0 in the second leg of their second round of Champions League qualifying on Tuesday night and after the clash, Lennon re-iterated his stance on the QPR, Norwich City and Nottingham Forest target.
"I spoke to him today and asked him how he was feeling. He said he could do with some game-time, and that's exactly what we did," he said.
"He's not given me any indication either way, so no news is good news on that front. If I've got him here for next week, I'll be delighted.
"It's a better squad with Gary in it. From our point of view we want him to stay, and if we can persuade him to stay we will do everything we can to do that.
"I think (Celtic chief) Peter (Lawwell) was speaking to Nottingham today to tell them that he's not for sale, or if he is for sale they are going to have to come back with a sizeable offer.
"He was excellent tonight and he has been for the last 12 or 13 months now."
