Argentina and Spain have had to make two huge changes to their kits for their Olympic football tournament.
The competition in Paris and other surrounding areas, kicked off on Wednesday, with all 16 teams in action.
Argentina and Spain are two of the favourites for the tournament, though the latter suffered one of the most controversial defeats in history against Morocco in Saint-Etienne.

All countries have to comply to with Olympic regulations and have their national flag as opposed to their football logo.
But there are also additional rules in place which Argentina and Spain, both with kits manufactured by Adidas, have had to adhere to.
As highlighted by Footy Headlines, there are notable differences in their regular shirts due to the stance taken by the IOC (International Olympic committee) when it comes to branding.
At both recent Copa America and Euro 2024 tournaments, the kits had large Adidas logos on the right side of the shirt.
However, for the Olympic tournament they have had to be made considerably smaller.
FIFA and the IOC allow for the same logo size of 20cm squared but calculate the measurements in a different way.
In addition, only one form of branding is permitted - meaning the iconic Adidas three stripes have been completely removed from the tops.
Iraq, who also have a partnership with Adidas, have also had to make the necessary adjustments such is the strictness on sponsorship.
There is also only one manufacturer technology identifier allowed, meaning even the authentic badge at the bottom of the shirt has been removed and only the Heat.Rdy stamp is present.
Other kits in the tournament have been designed by the likes of Nike and Puma - though the latter's shirts are the cheaper, thinner teamwear options as opposed to the traditional strips which are of a much better quality.
