Former Real Madrid coach Julen Lopetegui is tightlipped on his relationship with Isco.
Isco battled for minutes at the start of the season under Lopetegui and his problems have continued under Santiago Solari.
Lopetegui said: "I've talked to some players, I talked to everyone when I left, with some we send messages from time to time, I'm not going to give my opinion about any player, it would be irresponsible, I have a tremendous respect for the people who are there now."
On Isco he added: "I can give you my opinion on the footballer, it is already well known, he is unbeatable.
"My spoiled child is not the word, what I say or do not say is my business."
