Celtic manager Neil Lennon and chief executive Peter Lawwell have thanked Johan Mjallby for his loyal service to the club.
The Swede will leave his role as Hoops assistant coach at the culmination of the current season, ending a four-year coaching partnership at Parkhead, in which he has seen the side clinch three Scottish titles.
In the wake of former Celtic defender Mjallby's decision, Lennon was quick to thank his colleague for the work he has done with the Glasgow giants since 2010.
"I will be very sad to see Johan leave the club. He has given us such great service over a number of years and he will always be a big part of Celtic," Lennon told the club's official website.
"When I was given the chance to be in charge of the team, Johan was the obvious choice to join me in tackling the challenges ahead and from day one, he has been a very important part of our success.
"He was always respected by players and our supporters, who knew how committed he was to Celtic. Johan is a great man and will always be a great friend.
"I know whatever challenge Johan chooses next, he will be a great success and I wish him and his family nothing but good fortune for the future."
Lawwell added: "We wish Johan absolute success. Johan is a man who has given Celtic so much. He has shown dedication to the club and has demonstrated absolute professionalism throughout his association with Celtic.
"As a player and in management he has given us his total commitment, in recent years working closely with Neil to achieve great things for the club.
"On behalf of the board of Celtic we thank Johan for all he has given Celtic and wish him and his family the very best for the future."
