Official tournament regulations: FIFA designated England as the official home team for this World Cup semi-final clash because they occupy the upper side of the tournament bracket.

Because England will be sporting their traditional all-white home kit, Argentina's famous sky-blue-and-white striped jersey presents an immediate visual clash that violates tournament guidelines prioritising broadcast clarity for television spectators.

Special Argentine request: Rather than waiting for a standard administrative mandate from tournament organisers, the Argentine Football Association proactively submitted a formal appeal to secure their alternative navy blue jersey.

This was approved on Monday.

Psychological mind games: Opting for the dark blue jersey is widely seen as a clever psychological strategy designed by Lionel Scaloni's squad to gain a mental edge over their long-standing rivals.
