There's something enigmatic about Inter Milan that makes them a puzzle for Europe's elite. They've reached the finals of the Champions League, leaving behind the likes of Manchester City, Arsenal, Feyenoord, Bayern Munich, and Barcelona—all teams that failed to defeat them. This formidable squad turns every match into a strategic battle, often surprising those who approach them as favorites, perhaps due to their unique approach to ball control and attack.

Inter Milan is not just a team; it's akin to a challenging dental appointment, embodying the joy of being untouchable. "If we play our game, we are unbeatable," declared Henrikh Mkhitaryan, who has transformed from an attacking midfielder to a relentless force. This statement has been his mantra in recent months, often revisiting it: "I see how hard my teammates play and sweat. We are a very strong team," he shared before facing Bayern Munich in the quarter-finals.

The Armenian midfielder, 36, is indispensable in a lineup where key players include the goalkeeper Sommer (36) and the defensive leader Acerbi (37). Inter's squad boasts an average age of 30 years and 19 days—the highest among the 36 teams competing in this season's Champions League.

Beyond statistics lies the impression that Inter is a haven for players once thought past their prime, like Hakan Çalhanoglu, 31, a classic Turkish playmaker known for his set-piece precision and creative vision. His career blossomed in the Bundesliga, aided by his German diaspora upbringing. In summer 2014, Bayer Leverkusen paid 15 million euros for him from Hamburg, and three years later, Milan acquired him for 23 million. When his contract ended, he joined Inter, where Simone Inzaghi repositioned him, enhancing his strategic perspective. Çalhanoglu now likens himself to Pirlo, and his self-assurance is evident. "I'm the best organizing midfielder in the world," he claimed during the last Euro Cup, ranking himself above Rodri, Kroos, Kimmich, and Enzo Fernández.

Çalhanoglu and Mkhitaryan form an unexpected trio with Nicoló Barella, now a dynamic engine. Inzaghi holds the keys to success, emphasizing collective struggle against Bayern. Formerly a reliable striker with nearly 200 Serie A matches, mostly with Lazio, Inzaghi lived in his brother Pippo's shadow. Yet, as a coach, he's a proven winner, amassing nine titles, including a league, two cups, and three super cups with Inter, pushing Manchester City to the brink in the Champions League final two years ago.

Inzaghi has evolved the team, securing domestic glory and now vying for European triumph, despite financial challenges. Last season's continental runner-up finish led to an 85 million euro loss, followed by another 140 million in debt. Ownership changed last year when the Chinese investor group failed to repay a 395 million euro loan, allowing Oaktree Capital Management to take control, retaining familiar figures like Giuseppe Marotta and Javier Zanetti. These experts sold Onana to Manchester United for 50 million euros, replacing him with Yan Sommer for seven million from Bayern, showcasing their mastery.

Sommer is one of two notable additions since Inter's last final appearance. The other is Marcus Thuram, replacing Edin Dzeko and Romelu Lukaku, partnering with Lautaro Martínez up front. Thuram represents another redemption story, joining on a free transfer. It's another smart move, reminiscent of Achraf's sale to PSG for 68 million euros, succeeded by Dumfries, costing 14.
