Just announced. Henrik Larsson favourite to replace him.
Neil Lennon is to part company with Celtic after four years as manager following talks about his future.
It is understood that the former club captain had been considering his position for some time despite securing a third straight Scottish title.
He has been concerned about his playing budget for next season.
The 42-year-old Northern Irishman took charge of the Glasgow club in 2010, leading them to three league titles and two Scottish Cups.
Lennon, who also previously led Celtic to Champions League last 16, is believed to have been concerned that his present side would not be able to negotiate three rounds of qualifying next season.
