Jesse Marsch, the outspoken head coach of the Canadian national team, has never been one to hold back—and his latest comments are no exception. The former Leeds United and RB Leipzig boss has taken aim at newly appointed Tottenham Hotspur manager Roberto De Zerbi, unleashing a blistering critique over how the Italian handled Canadian midfielder Ismaël Koné during their time together at Marseille.

Since taking the reins of Canada's men's team in May 2024—a squad set to co-host the 2026 FIFA World Cup—Marsch has been tasked with developing a young, talented core. When asked recently on the "Call It What You Want" podcast which players have grown the most under his guidance, Marsch didn't hesitate to name a few standouts: Niko Sigur of Hajduk Split, Toronto FC's Richie Laryea, and most notably, Sassuolo's Ismaël Koné.

Marsch painted a vivid picture of Koné's journey, describing the 23-year-old midfielder as a "raw, talented person" when he first took over. "Since then, I've talked to him a lot about discipline and concentration—everything from his daily life, his nutrition, his sleep habits, to how he trains, how he shows up every day, and his overall intelligence on the pitch," Marsch explained.

The Canadian boss highlighted how Koné's move to Italy—joining a newly promoted Sassuolo side in a highly organized league—has been a turning point. "He's played an incredibly important role for them. They've had a great year, and he's had an incredible year. It would be easy to say Ismaël is the one who's improved most," Marsch said, noting that Koné's growth has come through significant adversity.

And that's where De Zerbi enters the picture. Marsch didn't mince words when discussing Koné's difficult spell under the now-Tottenham boss at Marseille. "It wasn't easy with De Zerbi in Marseille. De Zerbi was a real, real a—— with him," Marsch said bluntly. "But Ismaël stayed strong. He never doubted himself. He found a new situation, and now look at him flourishing."

For Canadian soccer fans and anyone following Koné's rise, this is a testament to resilience—and a reminder that a player's path isn't always smooth. Marsch's unfiltered praise for his midfielder's mental toughness, paired with his sharp criticism of De Zerbi's approach, adds a compelling layer to Koné's story. As the 2026 World Cup approaches, having players who can overcome tough environments and thrive under pressure is exactly what Canada needs—and Koné is proving he's built for the challenge.
