Manchester City boss Pep Guardiola has warned interested clubs off Kevin de Bruyne.
He told Universo Valdano: "He is really good, a very dynamic player.
"Marcelo Bielsa told me that Kevin is his favourite player. He does everything. I recently met his parents and you only understand how children are when you have met the parents. He is a really great player.
"His exit clause is €250 m. I'm sorry, he is not for sale."
