Celtic boss Neil Lennon has revealed that it will take a "sizeable" offer for the club to sell striker Gary Hooper.
Lennon told Sky Sports News: "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 Peter 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."
Hooper was left out of Lennon's starting lineup in their 5-0 win over Cliftonville in their Champions League third qualifying round clash, but he did come on for 25 minutes in the second half.
