Borussia Dortmund has shown interest in Mario Hermoso due to their defensive injuries. The club aims to take advantage of Hermoso's current situation at AS Roma, where he is not a regular starter. Transfer expert Matteo Moretto reported that Dortmund has initiated talks with AS Roma regarding a potential transfer of the 29-year-old Spaniard. Hermoso, who is under contract with Roma until 2027, is also being monitored by Bayer Leverkusen and Olympique Marseille. Both Borussia Dortmund and Bayer Leverkusen are looking to strengthen their defense by capitalizing on Hermoso's limited playing time at his current club.
