The blackout, which caused chaos across the Iberian Peninsula, failed to disrupt Barcelona's preparations.
Hansi Flick's squad trained as normal, determined to secure a strong result in the first leg and edge closer to a coveted Champions League final berth. "We're fully focused on the task at hand," Flick said after training. "The blackout hasn't affected our mindset or our work."
Fresh off their 32nd Copa del Rey triumph just days ago, Barcelona have wasted no time basking in glory. The squad returned to work within 48 hours of lifting the trophy in Seville, with their sights set on a dream treble.
"The Copa was a massive moment, but we're hungry for more," midfielder Pedri, said. "Inter are a tough side, but we're ready to give everything."
Barcelona's resolve has been echoed on X, where fans have praised the team's professionalism amid the blackout chaos. One user posted, "Barca training through a nationwide blackout? That's the mentality of champions. Bring on Inter!" Another wrote, "Flick's got this team locked in. Treble vibes are real."
Inter Milan, meanwhile, are no strangers to high-stakes European nights. Their manager, Simone Inzaghi, said his side were prepared for a "battle" in Barcelona.
"They're in top form, but we have our weapons," Inzaghi noted. The Nerazzurri's recent 2-0 Serie A win over Juventus has boosted their confidence heading into the tie.
For Barcelona, the semi-final represents a chance to cement their resurgence under Flick. With the Copa del Rey secured and La Liga dominance in sight, a strong performance against Inter could set the tone for a historic season.
The Catalans have not reached a Champions League final since 2015, and their supporters are daring to dream once more.
As the blackout saga fades, all eyes are on the Lluis Companys Olympic Stadium, where Barcelona aim to light up the pitch and take a step closer to European glory.
