Sky Sports pundit Paul Merson has described England's upcoming FIFA World Cup 2026 last-16 tie against co-hosts Mexico as a genuine 50-50 contest — one he believes the altitude alone could decide.

Thomas Tuchel's side booked their place in the round of 16 after coming from behind to beat DR Congo 2-1 in Atlanta on Wednesday. Their reward is a daunting trip to the Azteca stadium in Mexico City, a venue that holds 87,523 supporters and sits 7,200 feet above sea level.

The altitude factor

Merson was unequivocal about the challenge awaiting England in the Mexican capital. With Tuchel's squad arriving only two days before Monday's match, the former Arsenal midfielder insists there simply will not be enough time to adapt to the thin air.
