Rayo Vallecano face Crystal Palace in Leipzig on Wednesday 27 May — the most significant match in either club's history. The final comes as Pérez's side also navigate the run-in of a LaLiga season that has produced European football for the first time in a generation, with three games remaining and a trip to Mestalla on Saturday next.
Pérez spoke in his pre-match press conference ahead of the Valencia fixture.
"I would love it if there were screens and Vallecas took to the streets. It would move me to see those who cannot be in Germany."
On his winger Jorge De Frutos, who has become the symbol of Rayo's unlikely season and who harbours World Cup ambitions of his own.
"It is a parallel with what the team is experiencing collectively. Jorge is our figurehead. With how humble he is, sooner or later people notice, despite the badge. It is the same that has happened to all of us. I hope he can go to the World Cup."
The Valencia match carries its own significance — a win would confirm Rayo's top-flight survival mathematically, and keep alive a push for European qualification through the league.
"The objective, as the table stands, is even clearer. Those below are pressing and the three games that remain must be victories."
Pérez was candid about the physical toll a season across three competitions has taken on the squad.
"In the last month after having played in three competitions we have the fuel tank empty and above all the health at its limit. We have several injuries and a group of players who are playing on the inertia that comes from achieving the first objective."
On the nature of the Valencia game, he acknowledged the tactical complexity of facing Carlos Corberán's side.
"It is a complex match because the line-ups of both teams are difficult to predict given the variants. Both Corberán and I are two coaches with a clear identity and you have to have the capacity to adapt."
He was measured when asked about comparisons with Mikel Arteta and Luis Enrique, two managers whose names have been mentioned alongside his in the context of Spain's new coaching generation.
"They are not fair comparisons. I have just started and I have a long way to go to reach those levels."
On what Rayo's season represents in the broader picture of Spanish football.
"What Rayo has done is something historic. If we have reached the summit, we must look down and be aware of where we are so as to control the danger and not suffer from vertigo. We must not lose sight of our origins."
The Conference League final kicks off at 21:00 CET in Leipzig.
