Marcelo Bielsa’s side have remained silent in the transfer market following the signings of Junior Firpo and Kristoffer Klaesson last month.
Leeds are looking to sign a midfielder before the transfer window slams shut and have held talks with Huddersfield Town over a deal for Lewis O’Brien.
There have been suggestions that the Whites will also look to bring in a forward, with the club interested in several players, including Ryan Kent.
Club Brugge’s Lang is one player Leeds have been heavily linked with during the ongoing transfer window and they do hold a concrete interest in the winger.
According to Belgian magazine Sport/Voetbalmagazine, Club Brugge will only consider selling Lang for a hefty fee of €30m in the final days of the transfer window.
The Belgian outfit have maintained that Lang is not for sale this summer and will only consider parting ways with him if a club offer €30m.
Leeds have so far held off further signings as they feel their targets have been priced too high and it remains to be seen if they re-evaluate before the window closes.
