Barcelona lost veteran defender Inigo Martinez over the summer, as Saudi Arabian side Al-Nassr made a move for the Spanish international.

Hansi Flick has employed Alejandro Balde and Gerard Martin as his primary left-back, but the manager wants more coverage for the position.

The Catalan side have identified a 19-year-old Brazilian star as a potential replacement for Martinez.

According to Mundo Deportivo, Flick is keeping a close eye on Palmeiras' defender Luiz Benedetti.

The 19-year-old has also been identified as a target for Arsenal and Napoli, with the young Brazilian seen as a highly-rated prospect for European clubs.

Barcelona are keen on a move in January for the youngster, and the club are willing to pay €12m for the Benedetti.

Palmeiras want €15m for the Brazilian, but either fee would be a good investment for Barcelona.

Benedetti has shown the skill he has after making his debut for Palmeias' first-team earlier this season.

The youngster has shown great composure for Palmeiras, and he's expected to play in Brazil's U-20 squad for the World Cup.
