An early strike from Isaac Romero proved the difference on the day.
Sanchez Flores said: "Winning is always important, it gives you energy and strength for the next game. Winning two games in such a difficult season is a double joy, and today against a powerful rival, with many resources. It is a very important vitamin victory.
"There is something that the fans always appreciate, which is the will, the energy, the desire, the commitment; these are things that unite. And when they see a team in difficulties, against a difficult opponent capable of maintaining that, it is a huge joy."
On Isaac, he stated: "He fills us with energy and transmits to us the same as he does to you, a different air, desire to do things well, repeat the efforts, live the games minute by minute. He is permanently in uncomfortable areas, in risk areas and we have the great lucky that he is on our team and is so humble that that makes him even better."
