What were Lionel Messi and Zinedine Zidane doing together?

Barcelona star Lionel Messi and former Real Madrid coach Zinedine Zidane provoked plenty of speculation on social media on Friday after appearing in a photograph together.

Messi and Zidane have got together for a mysterious campaign which features a number of starts from the world of football — it’s not just those two.

Under the slogan ‘Otro’, the initiative has also seen other Barça players, like Luis Suarez, Lieke Martens and Toni Duggan, promote the brand.

There are also football legends involved, like David Beckham and Eric Cantona, while current players James Rodríguez, Neymar and Paulo Dybala also feature.

A whole cast of football players, some already retired, are involved in announcing that more light will be shed on this enigmatic project on Monday, Dec. 3… which coincides with the awarding of this year’s Ballon d’Or, although the two don’t appear related.
