"I think it's too expensive for Barca," Barnett told Catalan-based newspaper Sport. "To my knowledge, Barca have 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 Barca are working on the signing of Jordi Alba, a cheaper option."
Barnett did concede, however, that Spurs' failure to reach Europe's premier competition is an issue. He said: "Yes, it is clear that this is a problem. The big European clubs already know how much it would take to do a deal and therefore if you are interested you know what kind of offer has to be put on the table."
