I don't remember a week as a coach in which I've seen so much commitment, although it is one thing to see it in training and another to react in a game.
The hosts took Spain all the way to penalty shootout and won.
Luis Enrique believes his most pressing challenge as Spain coach is to evolve the team from the possession-focused identity, widely dubbed "tiki-taka", that saw them fail to breach a limited Russian Federation side and ultimately lose on penalties in the World Cup round of 16 despite enjoying 75 percent of the ball.
With the retirement of Andres Iniesta and Gerard Pique, it will be a new-look Spain under Enrique, who has omitted Atletico Madrid midfielder Koke and Barca left-back Jordi Alba.
Forgetting the heartbreak, Spain is now all set to start afresh.
Some have suggested that Spain boss Enrique should make a change in his side. "I think their game will be based on pace and pressing", he says. Players have been told to attend all team meals and not to bring smartphones when they are going to eat.
"The fact we have been a reference over the past decade means that everyone knows our national team", he said.
However, Ramos said there was renewed enthusiasm around the squad since Luis Enrique, who was a serial victor during his three seasons in charge of Barcelona, had take over.
Luis Enrique is also making plans to give Spain a psychological edge, according to Clotet. "(The players') conduct has been irreproachable", the former FC Barcelona manager said. I have my own personal challenge in that I have been a first choice under all of the national team coaches I've played under.
After the disappointment of the World Cup and with a number of key players no longer present in the dressing room, Luis Enrique will look to Valdes to help foster a strong team spirit and a winning mentality.
