Rules are rules that apply to Roger Federer at the Australian Open. The Swiss tennis star, who is already in the second round after three victorious victories, may still be so well-known in Melbourne, without his accreditation there is no progress even for him. Because the defending champion did not carry his name card with photo, a security guard stopped the 37-year-old in the catacombs of the Rod Laver Arena, as a video showed.

The 20-title most successful player in Grand Slam tournaments did not argue, but waited a moment before a member of his team helped him pass the conscientious keeper.

Federer meets Stefaons Tsitsipas from Greece at the first Grand Slam tournament of the year on Sunday (9am, CET). The 37-year-old is a favorite in the round of the top 16 and could triumph in Melbourne for the third year in a row this year. On the way, he could still meet his permanent rivals Rafael Nadal and Novak Djokovic. For Federer, a success at the Australian Open would be tantamount to his 100th tournament victory.
