Celtic have signed teenage central defender Leo Hjelde from Rosenborg.
The youngster, who turns 16 this summer, has agreed a three-year deal, subject to international approval.
Celtic say the initial plan is for Leo to join the reserve team squad, with a view to progressing towards the first-team.
Leo has represented his country at Under-16 level. His dad, Jon Olav Hjelde, was also a centre-half and played for both Rosenborg and Nottingham Forest.
Leo told the Celtic website: “It is a real honour to join Celtic, I had a number of options in front of me, but I know that Celtic is the right place for me.
“I have had the opportunity to speak to many people within the club, including the manager, Neil Lennon, and that has been fantastic.
“I know that the club will provide me with the best pathway for my future and I am really looking forward to the next few years of my career at such a fantastic club.”
The move follows the signing of 16-year-old goalkeeper Tobi Oluwayemi at the weekend. The Spurs academy star has represented England at youth level and is highly rated.
Tobi said: “I am delighted to be joining Celtic, it really is a dream come true and a massive opportunity for me.
“I know Karamoko very well and he has told all about Celtic, the size of the Club, the great supporters and the Club’s tradition for giving young players an opportunity.
“I am very excited about this move and I will be working hard, giving everything to the Club to progress and make the most of this great opportunity
