Celtic has seemingly become the perfect club for coaches and future managers to hone their craft.
Damien Duff is a winner with Shelbourne while Scott Brown is hunting down Falkirk in the Scottish Championship title race.
There have been countless others who have left Parkhead to succeed in management having learned from the likes of Neil Lennon, Ange Postecoglou and Brendan Rodgers.
It is the latter who has mentored a new record-breaker in Birmingham City manager Chris Davies in his first job as his own man in the dugout.

Chris Davies has broken records at Birmingham since leaving Celtic
Davies has this week guided the Blues to a League One playoff spot at the very least with 11 games in the division still to play.
The club confirmed the news earlier this week, much to the delight of their fanbase.
With the club’s financial power in the league they’re in, the title has been a demand. But Davies has still met expectations so far after his side beat Bristol Rovers 2-1 at Memorial Stadium.
That took Brum’s record this campaign to 37 wins which is the highest number of victories they have ever achieved in a single season in their history.
Birmingham now sit 11 points clear of cash-rich Wrexham who are second but the leaders still have two games in hand over their closest rivals.
Davies is looking to the future with the top two teams in the division earning automatic promotion to the Championship which would likely have been the owners’ bare minimum demand this term.

But Rodgers’ old protegé has done it in style.
Davies spent two years with the Irishman at Celtic before he would eventually leave with his gaffer for Leicester City.
This year he has made a conscious effort to pluck talent from Scottish football with former Hoops midfielder Tomoki Iwata tearing it up in League One.

The Japanese could be player of the year having also struck one of the goals of the season against Newcastle under Davies’ leadership.
Alex Cochrane (ex-Hearts), Scott Wright, Ben Davies and Kieran Dowell (ex-Rangers) and Lyndon Dykes are all at St Andrew’s right now.
The club also find themselves in the EFL Trophy Final.
