Arsenal have received a crystal-clear warning ahead of their Champions League clash with PSG: breaking down Willian Pacho won't be easy. The Parisian side showcased their defensive resilience in the second leg against Bayern Munich, holding the Bundesliga giants to just a single goal. At the heart of that performance was center-back Willian Pacho, who delivered a masterclass in defending.

Pacho played the full 90 minutes against Bayern, putting up eye-catching numbers: 13 defensive contributions, five clearances, six recoveries, a perfect 7-for-7 record in ground duels, and two interceptions, according to SofaScore. For PSG to secure back-to-back Champions League titles, they'll need another commanding display from the Ecuadorian. For Arsenal to edge past the French side, their attack must find a way past him—and that's no small task.

Former PSG defender Grégory Bourillon doesn't see the Gunners getting the better of Pacho. Speaking to So Foot, Bourillon heaped praise on the 24-year-old, who has become a cornerstone of PSG's defense since arriving in Paris. "He's the complete defender par excellence—whether it's his game intelligence, his physical presence, his duels, or his distribution," Bourillon said. "I find him to be a great complement to Marquinhos. His composure is truly contagious. Since he arrived, we've seen a more solid defense."

Bourillon also highlighted a quirky habit that underscores Pacho's calm demeanor on the pitch: chewing gum during play. "Did I chew that much gum? No, I didn't. It's dangerous! Isn't he afraid of choking? That attitude alone makes him seem like a calm guy with presence. I like his attitude on the pitch. With the way he projects, the attackers know they're in for a tough match."

For Arsenal, the message is clear: Pacho is a defender who thrives under pressure, and breaking through his composure will require every bit of creativity and precision their attack can muster. This Champions League showdown promises to be a true test of wills.
