“I know what the boys have told me, but it’s the ball that’s going to be used and anything else is merely to stomp your feet and make a fuss," Lopetegui, a former Barcelona and Real Madrid keeper, told a news conference on Monday.
“What we need to do is make the most of the positives, get over it and nothing else,” he added ahead of Tuesday's World Cup warm-up match between his side and Argentina and after Spain drew 1-1 with world champions Germany in a friendly on Friday.
National teams are using the Adidas Telstar 18 for the first time during the current round of internationals and the lack of grip and excessive movement through the air has been criticised.
Napoli keeper Reina, who is likely to be in the Spain squad for the Russia finals, was apoplectic, telling Diario AS: “There’s still time to change it" before the event kicks off.
“I bet you any money that there will be at least 35 goals scored from long range, because it's impossible to work out, not to mention it's covered in a plastic film that makes it difficult to hold on to,” Reina added.
Local media reported that the view was shared by the other keepers in the Spain squad, David de Gea and Kepa Arrizabalaga, with the former saying simply "No" when asked if he was a fan.
Germany forward Thomas Mueller scored against Spain on Friday with a long-range strike that appeared to deceive De Gea mid-flight, while German goalkeeper Ter Stegen branded the Telstar as “complicated”.
“Even though the ball's not always at fault, it's true that this one is a little bit complicated. You saw it in the goal we scored. It moves a lot and could be better,” he said.
“We’ve got no other option than to get used to it, though,” Ter Stegen added in agreement with Lopetegui.
