Just one year after leaving Aston Villa for Juventus, the 27-year-old midfielder is the focus of Leeds' ambitions to strengthen their team.
Italian club Juventus has set a £30 million price tag for Luiz and is looking to let him go due to a disappointing season.
Manchester United's manager, Ruben Amorim, is also interested in bringing Luiz back to England to help shape the team in his vision.
Signing Luiz would be a significant achievement for Leeds, as they aim to avoid the struggles faced by the three promoted teams in the 2024-25 season.
