Celtic winger Mikey Johnston has signed a new contract that ties him to the Scottish champions until the summer of 2023.
The 19-year-old has made nine first team appearances this season and his new deal represents a three-year extension to his previous contract.
The Scotland Under-21 international joined the Celtic youth academy at the age of nine and made his first team debut a month after his 17th birthday.
He told Celtic TV: "It's incredible for me and my family to commit my future here. It's unbelievable to have been part of this amazing club for 10 years and I'm excited for the future.
"I hope I can play my part. The club have given me a lot of confidence to go on and I'm going to try and repay them for that.
"I feel I've developed a lot since making my debut two seasons ago.
"It's hard coming in from a boy's game and into a man's game, but I feel I've improved a lot. You don't see a lot behind the scenes but I've improved a lot and I'm hoping I can kick on and show everyone that.
"There's been a lot of good players who have come up through the Celtic youth system and hopefully I can carry that on and go and show everyone what I'm about.
"You need to have confidence to be a winger at Celtic. The fans love players who are going to go out and try to entertain them and score goals and create assists. I have the confidence and I'm wanting to show that.
"Hopefully I can break into the team and start playing every week. I want to develop, improve and keep enjoying my football."
