Laporte had all his youth football for France before the former Athletic Bilbao pledged himself to Spain before the Euros last year.
Now at the World Cup, he says: "It was even reversed [ opinion]; instead of telling me that I am French, now I am even more appreciated, I am told the opposite.
"At the time, I made the decision to play for the Spanish national team. I was convinced, both by the coach and by the philosophy of the country, with which I feel in tune.
"I feel much more identified with the Spanish, and the Spanish give me back the affection that I felt for them at the time, and that I still feel today."
