Spain begin their Euro 2020 qualifying campaign against Norway on Saturday, before taking on Malta on Tuesday, and Luis Enrique is putting results ahead of experiments.
With these matches so important in terms of qualification for next summer's tournament, the coach doesn't want to take risks.
"There is no rush or haste," he said at a press conference on Friday night when asked working out his first-choice starting line-up.
"I would like to have a starting XI and some fixed players, but it'll be a long process.
"Now is not the time for tests of experiments, as we have two official matches ahead of us.
"We'll keep trying things, but we need to win.
"I have chosen the 23 players who I have seen in the best form.
"I'm going to stick with the same system, the 4-3-3."
The Asturian has already worked with the squad in friendlies and in the UEFA Nations League and he reflected on what he learned during his first months on the job.
"I am happy with what I've seen in the team," he said.
"Against England we were only beaten by three clear counter attacks, but the results are what they are.
"We need to improve, but I've seen from the start that there is hunger and ambition."
Looking back at the success of the Spain sides that won Euro 2008, the 2010 World Cup and Euro 2012, Luis Enrique is determined to emulate these triumphs.
"We've had three tournaments in which we've not reached the goals we were looking for," he told reporters.
"There are not many players left who have won titles with Spain and now we're looking to win new titles.
"Winning titles is hard, though.
"We need to build a new team and achieve good results, something that only comes with time.
"If we compare with the team that won two European Championships and a World Cup then we'd lose."
The first of these matches is against Norway and he broke down the style of play of the opposition.
"They have a great physical level and are stronger than us," he said.
"They play directly, with the full-backs getting involved and with good strikers like Joshua King.
"We'll have to limit their counter-attacking chances.
"As for stopping aerial play, the best way is for us to have the ball as long as possible."
The David de Gea question came up as well, and the goalkeeper received the backing of his coach.
"I have my three goalkeepers and I haven't changed them," he said.
"Time will tell if I've been mistaken or not."
Finally, he called for the fans to turn out and to support the team at Mestalla.
"I'd like to see the stadium full because we'll need the supporters' help," he said.
