Italian giants AC Milan and German outfit Borussia Monchengladbach are also in the hunt for his signature.
Bade joined Lens during the summer transfer window on a free transfer and has really impressed this season. He has made 16 Ligue 1 appearance so far, and has progressed immensely.
The report claims that the 20-year-old defender has no plans at the moment to leave the club. However, a departure next summer looks likely and he will continue to generate interest among his suitors should he manage to string together high-level performances for the rest of the season.
SL View: Good option for Leeds
Bade will be an excellent signing for the Whites. Almost everyone at Lens will agree that he has been a revelation in the first half of the season, and he is very popular among the fans.
He is good at tackling, ariel duels, interceptions and marshalls the defence like a leader. Bade is skilful with the ball at his feet, and he is adept at bringing the ball out from defence.
He is a very good passer of the ball as well, and in theory, should fit in seamlessly at Elland Road. However, Leeds are unlikely to delve into the market to buy a defender but could move for him in the summer.
