Everton have confirmed that they managed to complete a 12-month loan deal for teenage forward David Henen before Monday's transfer deadline.
The 18-year-old will be part of Roberto Martinez's squad this season after a complicated series of manoeuvres on deadline day.
Henen had looked likely to move to Goodison Park on a permanent deal from Belgian side Anderlecht after spending preseason training at Everton's Finch Farm base.
But the Belgium youth international instead signed for Greek champions Olympiakos -- who then immediately loaned him to Everton.
He will spend the season with Everton's under-21 side, who he will link up after playing for Belgium's under-19 side in matches against Israel and Hungary during this week's international break.
Martinez told Everton's official website: "As we had said previously, he's someone whose potential we recognise and at this stage he will go into the under-21 development squad. We are looking forward to working with him this season."
Luxembourg-born Henen joined the youth setup at Standard Liege when he was 12, then moved to Belgian rivals Anderlecht three years later.
The forward -- who was linked with a move to Manchester United when he was just 15 -- spent last season on loan at Monaco, where he played for their reserve side in the Championnat de France Amateur, the fourth tier of French football.
