Monchi left Villa this week after two years in England. However, he is not leaving completely as he will continue as a consultant for Villa's holding company, V Sports.
The Spaniard will also work with San Fernando, where he is club president.
He said, "I don't believe in projects that are built like skyscrapers. We have to build the foundation.
"The goal is to take it step by step, calmly, so that the team can grow in a solid and sustainable way. This baby has to learn to walk; we don't want it to run."
Asked about rumours of a return to Sevilla, he added: "Right now, Sevilla is in good hands. Any statement would be unfair to the people there."
Regarding the takeover option led by Fede Quintero and Antonio Lappí to buy Sevilla, Monchi did not hide his closeness to them.
He described Lappi as "my friend and a super successful businessman" and Quintero as "my brother".
Monchi acknowledged that he will listen and evaluate their proposal, but set a clear condition: "They have the enthusiasm, the ability, the passion, and above all, I believe they have credibility. I don't know what might happen in the future.
"Obviously, I will always have confidence that with them, they will do something good. I will listen to them and see what they propose. Everything has to be compatible with San Fernando."
