Thomas Tuchel has shrugged off concerns about England's treatment in Mexico ahead of their World Cup last-16 showdown, insisting the reception has been "nicer than I expected" and fans have been "friendly and respectful". England face the tournament co-hosts at 18:00 local time on Sunday in what promises to be a massive knockout encounter at the iconic Estadio Azteca.

Enhanced security surrounded the team's departure from their hotel on Saturday after Ecuador lodged a noise complaint with FIFA. Despite the presence of Mexico's National Guard and riot police, Tuchel praised the warm welcome. The Three Lions will need to handle more than just passionate support, however.

The altitude presents a genuine challenge, with the stadium sitting 7,220ft above sea level. Tuchel admitted feeling its effects since arriving Saturday, experiencing headaches and disrupted sleep. Players struggled initially in training but adapted progressively, though the coach acknowledged physical adaptation is impossible.

Tuchel expects Mexico to start aggressively given their home advantage, but believes England can overcome the early surge. With a six o'clock kick-off, he's confident his side will deliver a strong performance on the biggest stage. England's preparation appears focused despite the unique circumstances.
