Former FIFA president Sepp Blatter has joined the growing calls of fans to boycott the 2026 World Cup joint-host, the United States.

Sepp Blatter, who ran FIFA from 1998 until resigning in 2015 during a corruption scandal, posted on social media last week in support of Swiss lawyer Mark Pieth’s call to boycott World Cup 2026.

Pieth, an anti‑corruption expert and former head of FIFA’s governance committee, told Der Bund that supporters should avoid traveling to America for the tournament.

“If we consider everything we’ve discussed, there’s only one piece of advice for fans: Stay away from the USA,” Pieth said.

“You’ll see it better on TV anyway. And upon arrival, fans should expect that if they don’t please the officials, they’ll be put straight on the next flight home. If they’re lucky.”

Blatter quoted Pieth’s remarks on X, adding: “I think Mark Pieth is right to question this World Cup.”
