Celtic boss Brendan Rodgers has experienced a much more challenging time in his second stint as Hoops manager.
In his first stint in the dugout the Northern Irishman went largely unchallenged and dominated the Premiership between 2016 and 2019.
He was unbeaten in his first season with an incredible 106 points and went on to become the first manager in Premiership history to win back-to-back domestic trebles.
This was a feat which he would have almost certainly replicated for a third consecutive time the next season if he hadn't left Glasgow mid-term for a move to Leicester City as his successor Neil Lennon swept up the remaining trophies.
Overall, Rodgers was beaten just eight times in the league across his first two and a half years in the Celtic dugout, but he has already suffered three defeats this season on his return.
Rodgers is targeting a third league title this year which would take him level with Celtic managers such as Neil Lennon and Gordon Strachan.
With that in mind we take a look at the last 12 Celtic managers and how there careers have fared after leaving Glasgow.
5. Ronny Deila - Currently without a club
Ronny Deila won two league titles and a Scottish League Cup in an era where Rangers competed outside of the top-flight. Stepped down in 2016 after a narrow title triumph and has since managed New York City, Standard Liege and Club Brugge with mixed success. Was sacked from the Belgian outfit last month with them trailing behind Anderlecht in the Juplier Pro League title race. | Getty Images
