Barcelona have identified Borussia Dortmund's Raphael Guerreiro as a potential target in their hunt for a new left-back, according to a report.
The Camp Nou club have been strongly linked with Real Betis's Junior Firpo, but see Guerreiro as a potentially cheaper alternative.
According to AS, Barcelona are eager to create competition for Jordi Alba, but see Firpo as overpriced at £25m.
Guerreiro is also thought to be worth around £25m but, with his contract due to expire in 2020, Camp Nou chiefs believe that he could be signed at a cheaper price.
Guerreiro featured 32 times for Dortmund last season, scoring six goals as they pushed Bayern Munich in the Bundesliga title race.
