The agent of Gremio superkid Breno Melo was at the Nou Camp last weekend.
Globo Esporte says the 16 year-old's agent, Fernando Matos, was in Spain to see Barcelona defeat Atletico Madrid on Sunday.
Former Barca star Deco, who now acts as the club's South American scout, invited Matos to the Nou Camp, where he also met with president Joan Laporta.
Melo plays as a No10 and has a contract with Gremio to 2024, which carries a €40m buyout clause.
Known also as Breninho, the midfielder is pushing for senior football after developing physically over the last 12 months.
