Neil Lennon will not walk away from Celtic despite threats made against him, according to his agent Martin Reilly.
Lennon, 39, has had bullets sent to him through the post and a suspicious package addressed to him intercepted this season, leading to speculation about his future.
However, Reilly is confident that Lennon will stay at Celtic Park.
"He was a winner as a player and he's a winner as a manager,'' Reilly told the BBC. "As far as quitting as a manager goes, it's not in his nature.''
Reilly claims that Lennon would not discuss his future until the end of the season.
"We will have these discussions at the end of the season, but all Neil wants to do at the moment is concentrate on his job,'' he said. "He's got a contract to fight for, a six-month rolling contract, so he's got things like that to sort out in his life but he's got to put up with all this stuff off the park as well.
"He certainly hasn't spoken about quitting or walking out on the club, but I dare say it must have gone through his mind because it's certainly gone through mine.''
