Celtic coach Stevie Frail has left his post at Paradise, departing his position as the club's development coach.
The coach believes that now is the right time to leave his role and look for new challenges within the game.
Frail told his club's official site of his decision, explaining: "I have had a great time at Celtic over the past few years and enjoyed working for a great club with some really good players.
"But I felt the time was right to move on and look at some new challenges in football", Frail added.
The coach's work with Celtic's young players has been hailed by head of youth Chris McCart, who believes Frail has had a big impact on the players to successfully make the step up to the senior ranks at Celtic Park.

McCart said: "Stevie has done a great job for the club in recent seasons.
"He has been part of so many of our successes and brought through a lot of talented young players.
"Of course we are sad to see him leave but we wish Stevie very well in all his future ventures."
Frail does have coaching experience at a number of other clubs and was at Hearts from 2004, even stepping up to take charge of the first team when required in the 2007/08 campaign, when Valdas Ivanauskas left Tynecastle.
It remains to be seen who Celtic will turn to in order to replace Frail at the club.
