The Nerazzurri's resilience and clinical finishing, spearheaded by Benjamin Pavard's towering header, have kept their dreams of a Serie A, Champions League, and Italian Cup treble alive.
Bayern Munich, hampered by a crippling injury crisis, fought valiantly but fell short of overturning a 2-1 deficit from the first leg.
Manager Vincent Kompany lamented the absence of key players, including Hiroki Ito, Dayot Upamecano, Jamal Musiala, Manuel Neuer, Alphonso Davies, Kingsley Coman, and Aleksandar Pavlovic. "The big issue before Inter was injuries," Kompany said. "We had to understand what we could do without them."
Despite the setbacks, Bayern showed their quality. Harry Kane ignited hopes early in the second half, firing a precise shot into the bottom corner after a quiet first half.
"We had many scoring chances, more than Inter," Kompany said, reflecting on his team's performance. "The harsh reality is we will not play the Champions League final at home, but we know we did enough to win these games."
Inter, however, responded with ferocity. Lautaro Martinez capitalised on a loose ball from a corner to drill home an equaliser, becoming the first Inter player to score in five consecutive Champions League matches.
Moments later, Pavard rose above Bayern's defence to thunder a header past goalkeeper Daniel Peretz, restoring Inter's aggregate lead. "We're not putting any limits on how far we can go," Pavard said. "We have a great squad and want to win everything."
Bayern refused to relent. Eric Dier's looping header from a Serge Gnabry cross kept the tie alive, but Inter's defence, led by a heroic Alessandro Bastoni, held firm in stoppage time.
Marcus Thuram, exhausted after the match, admitted, "We were all a bit dead at the end," but the San Siro erupted as Inter extended their 15-match unbeaten home run in the Champions League, the longest active streak in the competition.
Thomas Muller, in what may be his final Champions League campaign with Bayern, expressed disappointment at missing the final at the Allianz Arena. "We gave everything against the best team in Italy," Muller said. "The fans saw we fought, but it's a pity the final was in Munich."
Inter's path to glory now leads to a semi-final clash with Barcelona, a test of their treble ambitions.
Recent updates from Inter's official X account highlight the team's focus, with manager Simone Inzaghi praising the squad's "heart and determination" in a post-match statement.
Meanwhile, Bayern's attention turns to the Bundesliga, where they remain frontrunners, with Kompany vowing to "learn and rebuild" for the challenges ahead.
For Inter, the San Siro remains a fortress, and their Champions League journey continues with no ceiling in sight.
