The Catalan side powered to the La Liga title last season and have strengthened their options upfront, signing Brazilian hotshot Neymar in hopes of retaining the championship.
However, the Barcelona rear-guard remains an area of concern, with rumoured target Thiago Silva of Paris Saint-Germain recently declaring his intention to stay with the Ligue 1 winners, leaving Chelsea's David Luiz to lead Gerardo Martino's shopping list.
Pique explained to Marca that the club were only interested in players who could fit into their characteristic style of possession football.
"Barcelona always needs special players, and I'm not just talking about centre-backs," he stated.
"The player has to be cast from a different mould because our footballing style is unique and it's difficult to find that specific centre-half that we're looking for."
Midfielder Cesc Fabregas has been linked with Premier League champions Manchester United throughout the summer, but Pique reiterated that his compatriot was happy to stay at the Camp Nou and the club wished to keep him.
"He's always looked relaxed to me," Pique shared.
"With him being such a good player it's to be expected that there are offers on the table, but he's said it and I'll confirm it. He's staying because it's his dream and we're happy that's how things are."
