Arsenal fullback Hector Bellerin is on the radar of Barcelona.
Don Balon says Barca are preparing to lose senior fullback Dani Alves this summer and are considering alternatives.
Bellerin is high on their shortlist. The Spaniard came through the La Masia system and enjoyed an outstanding campaign this season with Arsenal.
Celta Vigo youngster Jonny Castro and AS Monaco's Fabinho are also under consideration.
Fabinho is a former Real Madrid Castilla player.
