Leeds sporting director Nicola Salerno believes fans will soon see the best of Adryan.
Leeds pulled off one of the surprise deals of the summer when they secured the season long loan of Brazilian prospect Adryan.
The Flamengo owned star had previously been on loan with Cagliari, and is yet to make his debut for Leeds.
He has however been on the substitutes bench in recent matches, and it is likely to only be a matter of time before he makes a Championship appearance.
Sporting director Nicola Salerno agrees, and pledges the attacking midfielder will become a key player for the club.
He told TMW: "There are still bureaucratic details to be resolved. The boy is training. He came at a period of difficulty. Soon we will see the protagonist."
Salerno did not go into details regarding the issues, but it is unlikely to be anything to do with his registration with the Football League, as he has been cleared to be named on the bench in recent games.
It is not a major issue he appears concerned with, confident the youngster will soon be in the team.
He also had kind words to say about attacker Souleymane Doukara, who has impressed since returning from an injury sustained in August.
"He is a top attacker, he offers features maybe other teams do not have. When teams are getting tired he can make a difference."
