Real Sociedad president Jokin Aperribay has warned Real Madrid off midfielder Asier Illarramendi.

A move to Madrid appeared a done deal earlier this week, but Aperribay insists their young star is not for sale.

"Illarramendi continues today with Real Sociedad. There has been a conversation with Madrid but we have said that we will not negotiate.

"We are not negotiating with Real Madrid or anyone else," said Aperribay.
