MEXICO CITY — Decades after hosting victories by Pele’s Brazil and Diego Maradona’s Argentina, Mexico City’s legendary Azteca Stadium is undergoing a major revamp as it prepares to feature in an unprecedented third World Cup.

Mexico’s previous World Cups are widely regarded as two of the best ever, evoking the magic of Pele and the 1970 Brazil team and the genius of Maradona in the 1986 tournament won by Argentina.

But the Azteca’s glory has since faded, leaving the six-decade-old stadium in need of an overhaul before the 2026 World Cup, which Mexico will co-host with the United States and Canada.

Construction has progressed “considerably,” according to officials at the stadium, which will be the venue for five World Cup matches including the opening clash on June 11.

With much of the renovation kept under wraps, even the man who oversaw the original construction of what he calls “an icon of Mexican architecture and engineering” is unsure what to expect.
