Isco admitted he feels more confident playing with the Spanish national team than he does Real Madrid.
Isco's standing with Zinedine Zidane has varied over their tenure working together. Isco scored a hattrick in Spain's 6-1 win over Argentina on Tuesday.
"In Madrid I don't have the confidence a player needs,'' Isco said in a postmatch interview with Marca. "The matches with the national team give me life. Here I have the confidence of the coach.
"I want to show that I'm a good player. Lopetegui shows me confidence with the minutes he gives me.
"Maybe I'm the problem in Madrid. I don't know how to win Zidane's confidence.''
