Spanish club Barcelona has shown interest in signing Borussia Dortmund defender Julian Ryerson, as part of their efforts to strengthen the defense in the upcoming period, according to German media reports.

Barcelona is looking for a replacement player in the full-back position who can contribute effectively and ease the burden on the Frenchman Jules Koundé, whom the coach consistently relies on as a key player amid the intense match schedule and numerous commitments.

Norwegian international player Ryerson is considered one of the standout elements at Borussia Dortmund due to his tactical flexibility and ability to play in multiple defensive positions, making him a suitable option for the "ready substitute" concept that the Catalan club is seeking.

It is noted that this information came according to Sky Sports, without any indication so far of official negotiations between the two parties, amid anticipation of what the coming weeks may bring in the transfer market.
