The pair were close friends and also worked together at Barcelona, Celta Vigo and Roma but Moreno appears upset at the manner of his departure.
He revealed he felt "bittersweet" about getting the role and, in September, said he would be happy to step aside if Enrique found himself able to return, insisting that friendship came above all else. He has always been the leader of our project and has a contract until the  World Cup in Qatar.
With the return of Luis Enrique, it is already the fifth term (for four breeders) since the start of summer 2016 Vicente del Bosque, crowned world champion in 2010.
According to Marca, the players were left speechless and in tears after Moreno had let them know the latest.
Doubts grew about Moreno's future when federation president Rubiales declined to say whether he would be in charge at Euro 2020. But he did not come, just two lawyers.
Questions about Moreno's suitability for the role began to emerge following sluggish 1-1 draws away to Norway and Sweden in October, although Spain responded to those results by hammering Malta 7-0 on Friday to clinch top spot in Group F.
Enrique decided not to renew his contract when it expired in June 2017, before having a 13-month sabbatical prior to be appointed Spain boss.
"On Monday, Robert sent us a message saying he wanted to leave so as not to hinder the return of Luis Enrique". I have always said that, and have always been honest, nobody can feel tricked. "But I repeat that Robert Moreno told us he'd spoken with Luis Enrique, who had told him he wanted to return". We observed out via Moreno that Enrique desired back.
Spain vs Romania conflict in Euro 2020 Qualifiers will probably be performed on November 19, 2019 (Tuesday) as per Indian time.
But Luis Enrique will have key decisions to make in the coming months after Moreno's spell was characterised more by experimentation than either continuity or cohesion.
He was in charge for the Nations League, where Spain failed to reach the semi-finals, and remained in place for the beginning of their Euro 2020 qualifying campaign.
Rubiales said it was in Enrique's hands as to who he would prefer as his assistant. We thank him for his work.
