Palermo forward Paulo Dybala was present at the Camp Nou on Sunday to watch Barcelona beat Real Madrid in El Clasico.
The 21-year-old is currently one of the most in-demand attackers in world football following his exploits for his Italian club this season – netting 12 goals in 27 games.
Barcelona are said to be strong favourites to sign the Argentine and speculation has gathered pace after he was pictured in the crowd during Sunday's La Liga clash.
Arsenal are also said to be interested in Dybala, but it is understood that the player favours a move to the Camp Nou.
The forward joined Palermo from Instituto in 2012.
