Real Madrid chief Emilio Butragueno ducked questions about Isco after their Champions League win at AS Roma.
Real coach Santiago Solari dumped Isco for the 2-0 triumph at the Olimpico.
"In technical decisions I do not enter nor must enter into it," said Butragueno.
"It is a complete squad and Solari makes the decisions. So I should not enter."
Pushed further, he added: "I insist, really. They are matters of Solari. We must not enter."
Isco has not been a starter in any of the five games that Solari has been in charge.
