Borussia Dortmund are eyeing Manchester United fullback Sergio Reguilon.
Reguilon is currently on-loan at United from Tottenham, with the deal carrying a January break clause.
Sky Deutschland says Borussia Dortmund are looking for a left-sided wing-back and are considering Reguiln.
The Spaniard could therefore end his loan with United and move to Germany.
Reguilon's time with United has been hit by injury.
