Summer speaks exclusively to our new number 2 Kolo Toure for Celtic TV.
Having helped Celtic secure the Glasgow Cup last season, Kieran Tierney has progressed through from the Development Squad to the Celtic first team.
Capable of playing at left-back, Tierney is best suited to attacking, with his pace and crossing ability proving to be valuable assets for Stevie Frail's Young Hoops.
The Wishaw-winger also became a YouTube sensation last year when his goal from inside his own penalty box against Hearts was featured on countless news websites.
Having made his senior debut in a pre-season friendly against Tottenham Hotspur, Tierney caught the eye of Ronny Deila, being named in two senior squads for SPFL Scottish Premiership fixtures.
Tierney was handed his Celtic debut as a substitute when he replaced Emilio Izaguirre after 81' against Dundee at Dens Park.
This was followed by his full senior debut when he started at left-back at St Johnstone's McDiarmid Park.
And, after making an impact on the Celtic first team, Tierney rounded off his Development Squad season by helping to secure the Scottish Youth Cup for Celtic with a win against Rangers in the final at Hampden.
Tierney's progression at Celtic was again highlighted when he was given his home debut, starting against Ross County in the opening game of the 2015/16 season.
In recognition of his progress at the club, Tierney signed a new four-year deal at Paradise.
