Celtic manager Martin O'Neill has expressed his delight at beating off competition to sign two teenage prospects from KR Reykjavik.
Celtic manager Martin O'Neill was impressed by the pair on trial
Midfielder Theodor Elmar Bjarnason and striker Kjartan Henry Finnbogason have agreed two-and-a-half year deals.
And O'Neill told his club's website: "Both have very good potential and I know there has been a bit of interest."
Chief executive Peter Lawwall said: "It fits in with our policy in terms of youth development."
The 17-year-old Bjarnason told the Daily Express: "I have been on trial with quite a few clubs.
"And Brondby, Heerenveen, Feyenoord and Stoke all offered me a contract. But, after coming to Celtic, I had made up my mind where I wanted to go."
Celtic are likely to have to pay a fee for 18-year-old Finnbogason, who was also on trial with Bordeaux and has been capped for Iceland at Under-21 level, as he still has a year of his contract to run.
There will also be compensation to pay for Bjarnason, who has played for his national Under-19 side, even though his deal ended this season.
