Barcelona are weighing up several offers for Alexis Sanchez but have no intention of selling Pedro Rodriguez, according to sporting director Andoni Zubizarreta.
He also insisted that Xavi Hernandez, who had appeared set to exit the club, could remain at the Camp Nou.
Barca are currently reshaping the squad following the appointment of Luis Enrique and have made several signings already, with Ivan Rakitic arriving in midfield and goalkeepers Claudio Bravo and Marc-Andre ter Stegen joining the club.
Victor Valdes and Carles Puyol have already exited, while Cesc Fabregas has been sold to Chelsea, but there are expected to be other high-profile departures.
There has been speculation that Chile international Sanchez could be included in a part-exchange offer for Luis Suarez. Zubizarreta praised the Liverpool striker but remained coy over whether Sanchez would stay on.
"There have been offers from clubs [for Sanchez], but I don't know how it will end," he said in quotes reported by AS.com. "We're looking for a solution that will be good for everybody."
Pedro has also been linked with a move away from the club, but Zubizarreta said: "He's not for sale. He's going to be part of the plans for many years."
Xavi was believed to be heading for Qatar club Al Arabi this summer after coach Dan Petrescu said he has signed a pre-contract.
Speculation has since cooled about the move, and Zubizarreta said he is hopeful that the Spain international will soon commit his future to Barcelona.
He said: "Barca has taught a lot of us that nobody is indispensable, but Xavi is an icon. He's not just any player. He's our No. 6. We need to have an open conversation with him.
"If he stays he'll compete with the rest for his place and he'll be excellent. If he goes we'll try and do it in the best way possible. But as of July 1, 201, Xavi is with us."
Following the retirement of Puyol, Barca are believed to be keen to add a new centre-back to their ranks this summer, with the likes of Paris Saint-Germain's Marquinhos and Roma's Mehdi Benatia having been linked with a switch.
"It's obvious that we're working to reinforce that position," Zubizarreta said. "We're clear about what we want and we know who are our targets are, but every European club is looking for reinforcements in this position.
"There are a lot of good central defenders, but the level demanded by Barcelona is higher than that. When we look at the market we see that we've got one of the best central defenders in the world. [Gerard] Pique, at his best, is an amazing central defender. We hope to be able to have some news soon, but it's not just up to Barcelona."
However, Zubizarreta was insistent that Barcelona are not looking to bring in another new midfielder this summer.
"We want to have the best squad possible," he said. "We've signed Rafinha [Alcantara]. We've got Xavi, [Andres] Iniesta and also Sergi Roberto. From that point of view we don't see the need to bring in any more players in that area."
