Sardinian businessman Massimo Cellino has brought in compatriot Nicola Salerno to help recruit players for Leeds and the experienced transfer guru is attempting to utilise his extensive connections in Italy.
With deals for Marco Silvestri and Tommaso Bianchi being completed, Leeds may immediately move on to talented striker Mancosu.
It had appeared that Leeds were trailing Cagliari, Cellino's former club, in the race to snap up Mancosu, but the player's current club Trapani have denied any deal is done.
According to the Italian press, Mancosu may be dragging his feet because his intended destination is Leeds United.
Mancosu has an impressive scoring record in Italy's lower leagues and has 40 goals in just 68 appearances for Sicilian side Trapani since 2012.
