Jonathan Barnett believes Barca do not have the spending power to meet Spurs' price for the Welshman.
"I think it's too expensive for the club," he admitted to Sport.
"To my knowledge, the club [Barcelona] has not made any offer for him.
"If interested, they would have to put money on the table and then start talking. But it seems that the club is working on the signing of Jordi Alba, a cheaper option."
