Souness would like to sign the youngster as one for the future on a free transfer but there are potential problems with his current club Genoa who have failed to pay the player for the last few months.
"He's impressed us during his time here," said Souness. "At the minute, the situation is that he is contracted to Genoa but there's some dispute about that because he hasn't been paid for several months.
"As I understand it they have agreements in Italy and Portugal where you become a free agent if you don't get paid for three months."
