Barcelona have been leaning on their former Dutch stars for information on Ajax's brightest young players.
Ajax trio Matthijs de Ligt, Frenkie de Jong and Donny van de Beek are all on Barca's radar - with the Catalans pumping Ronald Koeman and the De Boers for information on the youngsters.
El Mundo Deportivo says Barca director Robert Fernandez has watched the three players and been assisted by right hand man Urbano Ortega and scouts Pep Boada and José Bakero.
Holland coach Koeman has kept his old club up to date on the trio's progress while former Ajax boss Frank de Boer and brother Ronald have also offered their opinion.
