Barcelona vice-president Jordi Mestre has spoken in glowing terms about Arsenal right-back Hector Bellerin to heighten speculation the LaLiga champions could try and bring him back to Camp Nou.
Bellerin is a product of Barca's feted youth system but left the club at 16 to work under Arsene Wenger.
"We've already seen him as a Cule [Barcelona follower]," Mestre said. "He's a great player, there's no doubt about that.
"Wenger convinced him to move and promised him something which we couldn't.
"We could not promise him that within two years he would be playing in Dani Alves' place."
Brazil international Alves is now with Juventus following a celebrated spell at Barca, with Sergi Roberto becoming the first-choice right-back.
"In many cases it's good that they leave to develop as players and then return [with that experience]," he added.
"Look at the cases of Cesc, [Gerard] Pique, [Jordi] Alba and Denis Suarez… I hope the same thing will happen with [Sergi] Samper too.
"It's positive that [these players] get minutes at other clubs. It is a dynamic which has always provided good results for players that carry the Barca DNA in their blood."
Bellerin's contract at Arsenal expires in 2019.
