Osasuna president Patxi Izko has reiterated that Jaroslav Plasil is not for sale.
Czech Republic midfielder Plasil has been linked with a move to the Premier League, just 12 months after joining Osasuna from Monaco.
Fulham and Bolton Wanderers have both been tipped to make offers for Plasil before the close of the transfer window.
Izko confirmed earlier this month that there had been no bids for the 26-year-old, who is a key part of coach Jose Angel Ziganda's plans.
And Osasuna supremo Izko has again stressed that the Primera Liga side have no intention of cashing in on Plasil.
"I only know the news that is in the press, but really, Osasuna is not interested in a sale," Izko told skysports.com.
"Plasil is an important player for our project."
