Celtic are one of the biggest clubs in Europe and without doubt the biggest club in Scotland as things stand.
The current side are chasing what would be an historic treble by the end of the season, which would be the perfect way for Ronny Deila to end his first season in charge of the club.
Here’s our assessment of how Deila compares alongside some of the club’s previous managers.
Ronny Deila – 5
Deila has done a good job since he became manager and has already won his first trophy with the side in the League Cup.
A winning percentage of 57.58% of games so far suggests that the side can be confident of protecting their lead in the Scottish Premiership as well as success in the Scottish Cup.
So far so good.
Neil Lennon – 7
Lennon oversaw a period at the club where his team had a win rate of 69.52% which enabled the side to win three league titles and two Scottish Cups while he was in charge.
There were also some famous victories in the Champions League, with the Bhoys famously getting the better of Barcelona at Parkhead while he was in charge.
A feisty and passionate style means he’ll always be held in high regard by most fans.
Tony Mowbray – 4
Mowbray had the lowest winning percentage out of the club’s last five managers and he failed to win a trophy while he was in charge of the team.
His team only won ten more games than they lost while he was in charge and the occasion of leading the club seemed to be a little bit too much for him.
It’s difficult to find any real highlights of his nine month spell as manager of the club.
Gordon Strachan – 7
Three league titles, one Scottish Cup and two Scottish League Cups were won in Strachan’s four years at the club.
His win rate as manager was 65.19%, which was impressive and kept Celtic at the top of the Scottish game for several years.
His teams knew how to get results in the difficult situations and big matches they faced and had he stayed in charge, they would have likely enjoyed more success.
Martin O’Neill – 8
The highest win rate of last five managers at 75.53% and the highest number of trophies; three league titles, three Scottish Cups and one Scottish League Cup.
O’Neill’s passion and enthusiasm throughout his career at the club was obvious and he was very consistent in terms of the success he had and the sort of performances that the Bhoys produced while he was in charge.
