Kieran Tierney or KT - he's one of our own. Kieran signed for Celtic at the age of 7 and progressed through the youth academy until making his first team debut in April 2015. The left back became a regular for The Hoops during the 15-16 season as 5 in a row was secured. Tierney continued to be a starter in both the 16-17 InVIncibles and 17-18 Double Treble winning teams, even captaining the club for the first time in the 5-0 League Cup win over Kilmarnock at Celtic Park. KT has won both the Players' and Writers' Young Player awards in Scotland for 3 consecutive seasons and has become a regular starter in the Scotland International side.
