There are some who have already grown used to Norway's new normal. Take last month's Champions League clash between Manchester City and RB Leipzig, when Erling Haaland netted five goals and broke another European record.
The verdict of Norway manager Stale Solbakken? 'I've seen it before,' he joked to Mail Sport the following day. Another senior figure in Norwegian football was equally nonplussed: a typical Tuesday, they laughed.
Now just another Wednesday awaits as Arsenal - led by Martin Odegaard - visit Haaland's Manchester City in the biggest game of this Premier League season.
