De La Fuente, who said teenage winger Lamine Yamal is fit after sitting out training, preferred to talk up Sunday’s final instead of focus on Argentina’s tactics.
“On Sunday we will watch a great show, two great national teams, very similar in some aspects in terms of attitudes and talent,” he added.
“I think it is going to be an amazing final, each team will try and take the game to their own side.
“I believe both Spain and Argentina will have a gameplan where talent and good football will rule over everything else.
“The referee will be there to support us and that the football is at a level expected of a World Cup final.”
Three-time world champions Argentina are looking to become the first team since Brazil in 1958 and 1962 to win back-to-back men’s World Cups.
Argentina boss Lionel Scaloni was not asked about his side’s tactics during his news conference on Friday.
However, he did talk about about his friendship with Spain boss De La Fuente, formed in 2017 when De la Fuente was an instructor as Scaloni studied for his professional coaching licence.
“He knows me from a personal point of view,” said Scaloni.
“We are friends but that doesn’t mean he knows what I am thinking about when it comes to football.
“We haven’t really been talking about playing style. We do have similar patterns of play when it comes to trying to have possession of the ball.
“I hope the game on Sunday will be a great show.”
