Shaun Maloney has described Mikey Johnston as an exceptional talent.
The former Celtic midfielder took up a coaching position with his old club at the start of the season and has worked closely with Johnston.
The teenager plays in a similar attacking role to Maloney and made a good impression in his two top team appearances, at home to St Johnstone and Kilmarnock.
Johnston earned rave reviews in the UEFA Youth League matches against Bayern Munich with Maloney hoping to pass on the coaching tips needed for Johnston to become a top team regular.
“He’s an exceptional talent for a player his age,” the Celtic coach told BBC Sportsound.
“There are definitely things he can improve on and we’ve spoken about them but he’s very good for his age.
“His produced a performance against Bayern Munich that I’ve not seen a Scottish player produce at that level, ever.
“It’s now up to Michael to decide how far he can go in the game.”
Like Callum McGregor and Kieran Tierney, Johnston has been with Celtic since an early age, after his debut against St Johnstone in May he signed a new three year contract.
After missing the start of the season through injury he has quickly returned to form and will feature in next week’s UEFA Youth League match away to Paris Saint Germain.
