With transfer speculation at full pace it would be easy to overlook perhaps the best source of first team players at Celtic.
Kieran Tierney, Callum McGregor and James Forrest are the standard bearers for the club academy with a handful of other prospects knocking at the door to reach that level.
Since he arrived at the club Brendan Rodgers has made it a priority to bring through players well schooled in the club with Tierney, Forrest and McGregor vindicating that policy in the Champions League home match against Bayern Munich.
The Irishman has given débuts to a number of players but it’s only once they’ve had a run of a dozen games or played in the Champions League that they can be considered top team material.
Tierney, Forrest and McGregor have shown that there are different routes into the first team to rack up over 100 appearances as well as accumulate an impressive medal tally.
The demands and expectations of the Celtic support are sky high but as Tierney has demonstrated when you bring a player through the system there is a special bond and identity that can bring about meteoric progress.
