At roughly 2,240 metres above sea level, the Azteca can punish teams that press too aggressively or lose concentration late in matches. The report says Tuchel has warned that England will not have enough time to acclimatise after travelling from Kansas City.
That makes preparation more important than any headline-grabbing remedy. England may need to manage the tempo, shorten pressing spells and protect its energy during Mexico’s strongest periods.
The report says sildenafil is not listed among WADA’s prohibited substances for 2026, but that does not turn it into a guaranteed performance aid or confirm an England plan. The drug affects blood vessels, and any decision would require medical supervision and a clear assessment of individual risk.
Previous football stories have added to the intrigue. Union de Santa Fe was reportedly linked with its use for an altitude fixture, while the English federation previously denied claims that the national team had considered it. The recurring pattern is clear: the rumour travels faster than the evidence.
England’s reported 2-1 win over the Democratic Republic of the Congo, with Harry Kane scoring twice after an early setback, provides a reminder that the team still has problems to solve. At the Azteca, defensive transitions and game management could matter as much as Kane’s finishing.
The next storyline will be whether England adapts its football to the altitude-and whether the Viagra speculation disappears once the team’s actual travel, training and medical plans become clearer.
