Everton have signed striker Joao Silva from Portuguese second division club Desportivo Das Aves.
The 20-year-old prospect has joined the Toffees on a three-year contract for an undisclosed fee.
Aves came to the attention of manager David Moyes while playing for Portugal's Under-20 side.
The 6ft 2in striker netted 14 goals in 32 league appearances last season.
He will join up with the Merseyside club at the beginning of July and will head off on their pre-season tour to Australia.
