There's still concern home fans will boo the stopper in Spain's World Cup qualifier with Liechtenstein.
"I don't want to look back, the reception when we arrived was fantastic," said Lopetegui.
"It was positive and hopefully the fans will be great in the stadium, too."
He added: "It's a really special game and you can sense that the players are motivated. There are three points at stake and so far everything is going as planned."
