The 19-year-old is enjoying his first full season as a regular in the Celtic first-team.

The left-back enjoyed such a wonderful year last season as part of Ronny Deila's squad that it is easy to forget that he only became a regular in the Hoops side from late November onward.

Therefore, with the 19-year-old enjoying his first full campaign as a key man within Rodgers' squad, the Northern Irishman has suggested that he is prepared to take a cautious approach with the Scotland international, despite his importance to the team.
"It's a balancing act with him because this is what would be his first full season and playing at this level there is a huge physical demand and of course mental demand as well," he said, as reported by STV.
"He's coping with it remarkably well. It's the job I gave myself, Kieran and the staff to monitor his loading and there will be times in games where I'll just have to take him out to protect him.
"This is about longevity for him and his career and we have a good squad of players we can put in and replace him if he has to come out."
It does arguably make sense to keep a close eye on Tierney's form to monitor whether he is starting to feel the effects of the demands of competing on several fronts, especially as they have a Champions League campaign to contend with this term.
The defender clearly has the potential to be an incredibly talented player for years to come, and Rodgers will want to avoid doing anything that may harm his chances of realising that potential.
