Sanchez Flores said he is pleased to be returning to further develop a project that he helped with in its earlier stages, but that his primary focus is avoiding relegation.
"I felt happy that the team kept growing," he said.
"And I'm happy to participate in the base of this project. Altogether, the fans, the players, the staff, to keep in the Premier League [in my first season]. It was the base for everything.
"Now I am happy to know the club is working very hard and Gino wants to put all the tools possible in the hands of the players and the staff. They have ambition and they want to still grow.
“The squad is OK. I am just learning a little bit more about the players, their ability, their skills, their mentality. All these things are interesting for the staff.
"The priority is results. We know the schedule is really bad now, but everything is possible with a positive mentality of the players, with the fans supporting us, with the passion, everything is possible.
"We need to be realistic. Now we are bottom, but the first mentality is we don't want to go back. We don't want relegation."
