Lennon has call on Celtic's Man Utd and Liverpool targets Wanyama, Hooper
"As I have said before, everyone has their price and I think I will have a say in the decision if a huge bid comes in for any of the players," said Lennon.
"But I don't want them to go. I want them to see this season out anyway and make a real fist of the competitions. There are not many teams still going on four fronts - including the Champions League - with half the season gone.
"Will I have the final say? I would like to think so, yeah. At the time when Aiden McGeady was leaving I felt it was good business
"It was a good offer and something where we could use the money on the team."
