Football Insider reports that the Championship side, who are pushing for promotion, are very interested in the right back.
Justin is very highly rated at Leicester, but he is second fiddle to the excellent Ricardo Pereira at the moment.
The 21-year-old has only played twice for the club this term, with both games coming in the EFL Cup.
He has not made his Premier League debut, with Pereira playing every league game.
Justin will be hoping to go on loan to gain first team experience, with a view to fighting for his place at Leicester next term.
