Borussia Mönchengladbach are reportedly seeking to strengthen their defense as part of a planned squad overhaul in the summer. A need for a central defender has emerged due to the expected free departure of Marvin Friedrich and uncertainty surrounding the future of loanee Kota Takai. Sky reports that the club has identified Luca Sirch from 1. FC Kaiserslautern as a potential target. The 26-year-old German centre-back will be available on a free transfer in the summer as his contract in Pfalz is expiring. Sirch, who joined Kaiserslautern in July 2024, is reportedly seeking to advance his career and is aiming for a move to the Bundesliga. However, concrete negotiations with Borussia Mönchengladbach have not yet started. During the current 2. Bundesliga season, Sirch has made 26 appearances, scored one goal, and provided four assists. His market value is €2.20m, according to Transfermarkt. FC Union Berlin, FC Augsburg, TSG Hoffenheim, and SV Werder Bremen have also been linked with the player.
