Koeman has since spoken of the chaos after defeat to Real Madrid on Sunday.
Tebas also commented: "It also happened to others and that should not happen. They are security issues, in this case of the club. We have called and we have shown our concern."
"We would have liked them to have continued here, but I would also like there to be other great players in Spain like Haaland or great coaches like Guardiola or Mourinho, but it is what it is.
"Their absence does not affect us internationally because we had four seasons sold out in terms of audiovisual rights. Soon we will announce some important deal that we have made in a country in the world where we have had a very important rise, despite the fact that Messi is not there."
