The former Roja striker has praised Vicente del Bosque's bench for giving the national team a depth which has contributed greatly to their successes in the last four years
The former Real Madrid striker reasoned that the fringe players can make just as big an impact as the regular starters in the team, citing the Euro 2008 and 2010 World Cup finals as an example.
He added such depth was missing in the past for Spain, including during his own time in the national team between 1998 and 2007 when he collected 47 caps and scored 27 goals.
"The difference nowadays is that the substitutes have the same potential as the first XI," Morientes told L'Equipe.
"They played the Euro 2008 final without David Villa, their top scorer, and they still won. They played the 2010 World Cup final with Fernando Torres, Jesus Navas and Cesc Fabregas on the bench, they came on during extra-time and they make the difference.
"[Against Netherlands] Navas is at the start of the decisive attacking move, Torres as well and Fabregas delivered the assist for Andres Iniesta.
"In what other team does one find such depth?"
Spain will take on Italy in the Euro 2012 final in Kiev on Sunday at 20:45CET.
