A recent report claimed that Barcelona were close to reaching an agreement with Gavi, who has become a key player for both his club and the Spanish national team this season.
Dembele's future is unclear, though, with the France international - out of contract next June - still being strongly linked with a move away from Camp Nou.
Speaking during the unveiling of Dani Alves on Wednesday, Laporta said that "talks are ongoing" over new contracts, and the club are 'hopeful' of being able to soon announce extensions.
"Hopefully we can achieve more renewals soon," said Laporta on Wednesday. "Talks are ongoing. We're working on this."
Manchester United, Chelsea and Juventus are all believed to be keeping a close eye on Dembele's situation, with the World Cup winner, as it stands, able to hold talks with foreign clubs in January. body check tags ::
