Ali Reghba has moved from Bohemians to Leicester City for an undisclosed fee subject to international clearance.
The attacker had trials with the Foxes over the winter but a deal did not materialise in time for the January transfer window.
Instead he penned a fresh one-year deal with Bohs, but the talented 19-year-old will now go back across the water to try and force his way into the first-team picture under Brendan Rodgers.
Reghba jets out to Armenia next week with Tom Mohan's Republic of Ireland Under-19s for the European Championships.
"Everyone at Bohemians wishes Ali the very best of luck in his move and in Armenia with the Under-19s," said Gysies boss Keith Long
"He’s a successful graduate of our Under-19s and underage system and we wish him the very best for the future."
