Hearts boss Robbie Neilson says that Newcastle United youngster Garang Kuol was at the club's training base this week.
The 18-year-old attacker, who joined from Australia this week, is likely to go out on loan.
The Magpies are in the process of working out the best team for Kuol to develop his talent for the rest of this season.
“He's a player we're interested in so he came up for a look around with his agent," said Neilson.
“He's got a number of clubs that are very interested in him.
"He's a huge prospect. He's one we've known about for quite a long time because he comes from the same team as Kye Rowles was at.
“The opportunity came to speak to him so we brought him up and we'll see where it goes. It's still at the very early stages. It will depend what other clubs are in for him."
