Celtic have confirmed Scotland Under-21 forward Mikey Johnston has signed a new five-year contract at the club.
A product of the youth academy, Johnston has made 45 first-team appearances, scoring 11 goals, with the new deal meaning the player will remain at the club until at least the summer of 2025.
The 20-year-old made his debut for Celtic in the 4-1 home win over St Johnstone on May 6, 2017, with his first goal coming in the 3-0 win at Celtic Park over Motherwell on December 19 a year later.
And on the final day of last season, he scored both goals in a 2-1 home win against Hearts as Neil Lennon's side lifted their eighth league title in a row.
This season, Johnston has continued to improve, scoring six goals in 17 outings including goals in the 3-1 Champions League away win over FK Sarajevo and the 3-1 Europa League win over Rennes.
