Everton have completed their third summer signing with forward David Henen signing a three-year contract with Roberto Martinez's side.
The Belgian youth international spent last season on loan at Goodison Park and was a regular for the club's Under-21 side under David Unsworth.
He was expected to sign for Everton from Anderlecht last summer after training with the club during pre-season. However, he ended up joining Olympiakos late in the transfer window before being immediately being loaned to Everton.
The 19-year-old is now an permanent Everton player on a three-year deal, with reports suggesting he could be sent out on loan to gain competitive experience.
Speaking upon signing for Everton, Henen said:
"I am so happy. Everton are a big club and I feel I can develop here.
"For a young player it is the best club because they try to develop youngsters. It is perfect for me."
Henen joins Tom Cleverley and Gerard Deulofeu in signing on at Goodison Park this summer as Martinez looks to get the majority of his business done early.
