City struck first through Julián Álvarez in the 12th minute, executing a low block that caught United cold on transition after an ill-timed pass from Bruno Fernandes went awry.

They seemed poised to double their advantage when Erling Haaland hit the post not long later — but it was United who would find their rhythm amidst adversity, buoyed by ferocious home support eager to spark life into their players' performance.

As halftime approached, Marcus Rashford broke free down the left flank with blistering pace and sent in a low cross that deflected off Rúben Dias’ foot — ending up in his own net for an unfortunate equalizer just before the break.

After half-time — Ten Hag adjusted tactics — opting for a more aggressive high press that pushed City deeper into their own territory, forcing mistakes and creating openings through quick counter-attacks.

Substitutions played a crucial role too; Anthony Martial came on for Scott McTominay around the hour mark and immediately added spark to an otherwise static attack against City's organized back line—his movement allowing others like Rashford to find space. So when Maguire rose above everyone else during one final corner kick deep into stoppage time, it felt like fate had been scripted hours earlier. This wasn’t just another win; this was redemption.

With tension thick in the air and seconds remaining on the clock, Maguire's thundering header found its way past Ederson — jubilation erupted while disbelief lingered among City's ranks.

But City weren’t without chances even after conceding; they pushed hard during injury time attempting to salvage pride through moments reminiscent of previous victories against fierce rivals—only to be denied by David De Gea’s heroics between posts.

Overall? This contest exemplified why these two clubs command such devoted followings across generations; rivalries forged under shared history will ignite forever amongst fans witnessing magic unfold—or heartbreak cascade onto seats grown damp from sweat and rain alike.

As supporters file out with thoughts swirling over this compelling clash—a glance towards upcoming fixtures holds promise too.” After all—each match has stakes intricately woven into respective campaigns ahead whether chasing silverware or survival.
