Full football stadium one night, packed boxing venue 24 hours later.
It sounds simple, but in reality the size of the task facing staff at London’s Wembley Stadium during the day between England against Peru at 8pm last Friday and Carl Froch against George Groves on Saturday night was enormous.
And an amazing timelapse video caught the whole transformation. Scroll down to watch it.
The video begins with Wembley looking how every football fan has seen it a million times, ready to host an international friendly and warm-up game for the 2014 World Cup.
As kick-off appraoches, the stadium fills with 90,000 football fans, desperate to see an England team who might challenge in Brazil.
The football then gets under way, with England beating Peru 3-0 thanks to goals from Daniel Sturridge, Gary Cahill and Phil Jagielka.
But as the stadium empties, the real work begins.
Under the night sky, the laying of the mats used to cover the hallowed turf starts.
Soon the whole pitch is covered, and ringside seats are put in place.
As the sun shines, the ring at centre of the stadium begins to emerge.
Soon boxing fans start to arrive, ready for the Froch versus Groves undercard.
Then the stadium is full again, less than 24 hours after the football match ended.
As darkness draws in, the fireworks and razmataz of big-time boxing comes to life. The scene is barely recognisable from the football match a day earlier.
But almost as soon as the excitement peaks, it starts to tail off, with the stadium emptying soon after Froch landed the savage eighth-round blow which ended the fight.
The video then ends as the clean-up begins after the boxing.
You imagine the Wembley Stadium manager endured a long few days of work overseeing the logistics of such a quick switch.
