Spain went into the 2018 FIFA World Cup without a coach after Julen Lopetegui, who had not lost a game in two years, was sacked on the eve of the World Cup.
Sunday morning brings an "exclusive" that reports Hierro won't be getting the job on a permanent basis, with Spain not impressing in the tournament and falling at the last 16 stage in a poor performance against Russian Federation.
The Spanish Football Federation (RFEF) announced his appointment on Monday and also named Jose Francisco Molina, a former Spain keeper, as their sporting director.
As Barcelona coach Luis Enrique worked with Spain internationals Jordi Alba, Sergio Busquets and Gerard Pique, as well as Andres Iniesta who has already announced his retirement from worldwide football.
In fact, Spain's only victory in Russian Federation came in the form of a 1-0 win over Iran who ensured that the European side had to fight hard for all three points.
Of the starting XI against Russian Federation, only Marco Asensio will be under 30 when the next World Cup comes around.
Spain have appointed a new national team manager - days after Rafa Benitez was linked with the job.
The 48-year-old won two La Liga titles and the Champions League with the Catalan side before stepping down last year.
Speaking at a press conference widely covered in the Spanish media, RFEF president Luis Rubiales said: "We have not spoken to anybody else - only Luis Enrique".
Luis Enrique is favourite to take over as Spain manager.
