As England and Mexico prepare for their World Cup showdown at the historic Azteca Stadium, the cultural fault line will center on a pub in Mexico City's Juarez neighborhood.
The Duke of Lisbon, managed by a British-Mexican team, serves fish and chips alongside chicken tikka masala. By kick-off, the venue will be a sea of green and white shirts.
"One side will leave happier than the other. But we hope we all have a good time," said Mexican co-manager Luis Pena.
The Azteca carries heavy history for England, the site of Diego Maradona's infamous "Hand of God" goal in 1986. Despite the stakes, English co-manager Alex Mahoney expects good spirits. "There's mutual respect which hopefully will still be in place on Sunday."
Binational families are navigating the rivalry. Englishman Matt Tyler and his Mexican wife Iris Hernandez have exchanged jokes all week, while their sons weigh their loyalties.
"We are Switzerland until Sunday," Hernandez said.
Tyler remained undeterred, stating his sons should back the better team, "which we all know is England." If England loses, he plans to switch from British ale to Mexican Victoria beer and tequila.
