'A huge advantage for Mexico' - England face an Azteca altitude problem

"It is one of the most beautiful fixtures you can have playing Mexico in the Azteca," said Thomas Tuchel after England booked their World Cup last 16 spot. But it is also one of the hardest fixtures in football.

England go to the 87,000 Azteca Stadium full of joy after Harry Kane's heroics against DR Congo - but not only do they have to play better against the co-hosts, they will be as testing an environment as they have faced in a generation.
