Calvin Brackelmann has attracted interest from two English clubs, including FC Middlesbrough, as reported by the portal 'eflanalysis.com'. Additionally, clubs from the Bundesliga are also interested in the centre-back. Brackelmann is contracted to Paderborn until 2026, and the club may consider selling him in the summer to secure a transfer fee, especially if financially strong representatives from England or Bundesliga clubs are vying for the 1.96-meter tall defender.
