Keylor Navas was dumped to the bench despite doing nothing wrong so far this season.
Lopetegui said, “We've got fantastic options in goal. Keylor played superbly in Girona and he's been recognised as the best goalkeeper by UEFA. We've got some idea of where we're going to go, but whatever we decide, we'll try and make sure it's the best option for the team.
“The word untouchable does not exist in football. We have a way of playing, some good alternatives on the pitch and the bench. Sometimes the guy who comes off the bench can make or break the game. We are thrilled with this team and we're going to keep working."
He added: "“We did not discuss plans. We knew Thibaut would play today, we'll see about the rest. We have great goalkeepers here and we want to find the best solutions, it is fantastic to have competition in any position."
