Retractable pitches, self-filling cups, LED scoreboards.
Plenty of stadiums may have more modern trimmings and fancier decor than Old Trafford, but none of that can match up to the history that is engrained into the bricks of Manchester United's home. It's a mesmerising and daunting place to visit as a visiting player or supporter, with its towering stands and massive capacity. A special place that remains the apex of British football.
United's players have done their best in recent seasons to ruin its aura by losing plenty of home matches and wrecking Old Trafford's reputation as a fortress. But as a piece of football architecture, it will always be in the upper echelons of the world's best, let alone the Premier League.
