The 2020-21 campaign delivered an instant return to the top flight for Espanyol as Los Pericos clinched the Segunda División championship, securing promotion back to La Liga at the first attempt. Under manager Vicente Moreno, they finished top, narrowly edging out rivals Mallorca on goal difference and scoring an impressive 71 goals. Spearheading the charge was the club's record signing, Raúl de Tomás, whose phenomenal haul of 23 goals earned him the league's Golden Boot and MVP award. This triumph, secured with four matches left to play, was a season built on attacking brilliance and remains a defining chapter of their resilient, swift comeback to the top tier.
