Cellino is locked in talks with Brazilian club Flamengo about signing their playmaker Adryan.
Manchester United made moves for the 20-year-old in 2012, while he has also been linked with Spanish giants Real Madrid and Barcelona.
Adryan is currently on loan at Cellino’s old club, Cagliari, after the Italian took him there in January.
Cellino, 58, revealed: “The player wants to come to Elland Road, so that is not the issue here. I know Adryan well and he is a special talent.
“But this is a complicated deal. There is still talking to do with Flamengo and the player’s agent.”
Adryan’s agent is due to meet Cellino at Elland Road today and a deal could be concluded before tonight’s game at home to Brighton.
Adryan has played for Brazil at every age level from the Under-15s to the Under-20s.
So far, he has been dubbed the new Zico, Romario and Kaka in his homeland.
