Barcelona are in advanced talks to sign NK Kustosija defender Mikayil Faye.
The Senegalese has been dubbed 'The Monster' and is a regular for NK Kustosija in Croatia's Second Division.
Barca have moved quickly to seal an agreement for Faye amid rival interest from Chelsea and Borussia Dortmund.
Ok Diario says Barca will pay 5m for the 18 year-old centre-half.
Barca chief Mateu Alemany has also reached personal terms with Faye's Spanish agent Juanma Lopez.
