Real Betis president Angel Haro admits they've turned down Isco.
The former Real Madrid midfielder is a free agent after being released from his contract at Sevilla before Christmas.
Haro said, "These are names that are there, logically he is a good player.
"He offers himself as more players offer, but being respectful of any player, I think we have a great squad and it is the group that has brought us here."
Haro made the decision, despite the knee injury suffered by Nabil Fekir last week.
