Barcelona president Joan Laporta said on Friday he is "moderately optimistic" Lionel Messi will stay but would not guarantee the future of Ronald Koeman, with further talks planned between club and coach next week.
Laporta also remained defiant over Barca's continuing membership of the European Super League, insisting they will not apologise and will take UEFA to court if fines are imposed on the three remaining clubs.
Messi's contract expires this summer, allowing the Argentinian to leave for free. Laporta admitted Barca's offer will be curbed by the club's financial problems but insisted talks are "going well".
"We can make an offer within our means," said Laporta in his first press conference since being voted in as president in March.
"He deserves more and could get a better contract somewhere else but I'm convinced he appreciates the efforts we are making. I think he is keen to stay. For Leo, it's not about money, it's about winning. And that's what we are working on."
Asked how optimistic he is that Messi will stay, Laporta answered: "Moderately optimistic." He added: "The new contract is going well but it's not done yet."
Laporta has also been talking to Koeman this week, with the Dutchman's future in doubt after a disappointing end to the season.
Koeman has a year left on his contract after only being appointed last year.
"We've always worked with great respect for Koeman," said Laporta.
"He still has a contract in place. We don't believe in transitional projects or seasons. We spoke to Koeman and we will continue to talk to him next week before making a decision."
Laporta said Koeman had recently gone to hospital for a heart problem and that it was important not to rush decisions.
"We are trying to come to an agreement over what we want for next season," Laporta added.
Pep Guardiola and Xavi Hernandez have both been mentioned as possible successors if Koeman leaves.
Asked if it was his dream to bring back Guardiola, Laporta said: "I am not here to talk about dreams, I am here to talk about reality."
He was also asked about Barcelona's continued involvement in the Europan Super League, despite nine of the 12 founding clubs quitting the project. Real Madrid and Juventus also remain attached.
