Barcelona could reportedly move for Stuttgart defender Borna Sosa during this summer's transfer window.
The Catalan outfit are widely expected to move for a new left-back in the upcoming market, with the club's head coach Xavi allegedly eager to sign competition for Jordi Alba for next season.
According to Kicker, Sosa has emerged as a genuine target for Barcelona, with the Croatia international potentially available for €25m (£20.9m) during the summer window.
The 24-year-old's future has been the subject of much speculation in recent weeks, with Chelsea, Aston Villa, Inter Milan and Tottenham Hotspur all said to be interested in his services.
The Croatian is primarily a left-back but has played as a left midfielder for the bulk of this season, scoring twice and providing eight assists in 25 appearances in all competitions.
Celta Vigo's Javi Galan, Benfica's Alex Grimaldo and Real Betis' Alex Moreno have also been linked with moves to Barcelona to boost their options at left-back.
Alba remains a key player for Barcelona, making 36 appearances in all competitions this term, but he recently turned 33, and the club are said to be looking to the future.
