Bayer Leverkusen want to buy Manchester United fullback Brandon Williams.
The 20-year-old has struggled for game time this season and has played just six minutes of Premier League football since the start of the 2020-21 campaign.
Sky Sports says Bayer want to bring in Williams on a permanent transfer - though the Red Devils will only negotiate over a loan deal.
The report says the Bundesliga side are looking for a replacement for loan defender Santiago Arias, who arrived from Atletico Madrid earlier this season but then broke his leg and suffered ankle ligament damage while away with Colombia.
Bayer were strongly linked with a move for Arsenal full-back Sead Kolasinac earlier this year, but a move for the former Schalke man failed to materialise before October's transfer deadline.
A move to Germany would be a major boost for Williams who may need to look away from Old Trafford if he wants to further his career.
