Bale has recently been strongly linked with a move to the Spanish giants.
“I do not know if Bale interests us,” Rosell told Al Jazeera.
“If I did, I would not say, because his price would go up. [Tottenham] would not ask for €40million [£33.2m], but €50m [£42.8m].
“In any case, even if we wanted him, we would never pay €40m for him.”
Bale’s current contract with Spurs is set to expire in the summer of 2015.
