New president Sandro Rosell has warned Arsenal that Barcelona will not pay over the odds for Cesc Fabregas.
The Spanish champions have already seen one bid for the Spain midfielder rejected by the north London club this summer.
Fabregas is reported to have told manager Arsene Wenger of his desire to leave the Gunners to rejoin his former club following seven years in the Premier League.
But following reports that Arsenal are holding out for a £40million fee for their unsettled captain, Rosell has issued a financial warning.
"We will never pay 50 or 60million (euros) for Cesc," he told Spanish radio."The whole world knows he wants to come and that we want to sign him.
"It's a topic that has become so public and that's the worst thing you can do with a transfer, because it makes the selling club raise their expectations and you end up paying over the odds."
Rosell's claim comes on the same day that he revealed that cash-flow problems were behind the sale of Dmytro Chygrynskiy back to former club Shakhtar Donetsk.
The 23-year-old defender has left the Camp Nou for a cut-price 15million euro fee just 11 months after joining Barcelona.
"This operation is necessary for the club, above all to solve some short-term cash-flow problems," Rosell told the club's official website.
"The coaching staff have been very understanding which we greatly appreciate. The club's finances are a priority right now."
