Messi, Lamine Yamal's baby photo goes viral ahead of their meeting in the WC final

When Joan Monfort took photos of Lionel Messi with a baby for a charity calendar almost 19 years ago, he knew that the long-haired young man was at the cusp of an amazing football career.

He could not have imagined though, that the little boy would one day have one of his own.

The baby in the photo – which has now gone viral – was none other than Lamine Yamal, the Spanish wunderkind who at 16 was showing such promise that he was already being compared to the greats of the sport.

Already the youngest to have played for Spain, he became the youngest player ever in the European Championship at the ongoing tournament in Germany.

The long-forgotten photo from 2007 resurfaced after Yamal’s father posted it on Instagram last week with the text “the beginning of two legends.”

Monfort, who currently works as a freelance photographer for The Associated Press and other media companies, said the photo shoot took place in the visitors’ locker room at Barcelona’s Camp Nou stadium in the fall of 2007, when Yamal was just a few months old.

Barcelona players posed with children and their families for a calendar as part of an annual charity drive by local newspaper Diario Sport and UNICEF.

Monfort was in charge of the photo shoots – and it just so happened that Messi was paired up with Yamal’s family.

His mother, who is from Equatorial Guinea, is next to Messi and the baby in one of the photos.

Messi was 20 at the time and already considered a big talent but it would take a couple more years before he made his mark as the most outstanding player of his generation in Barcelona and Argentina’s national team.

Like Messi, Yamal has gone through Barcelona's renowned La Masia youth academy. Despite his young age, he was one of Spain’s best players at the European Championship in Germany.

He has also been a key part of Spain's squad that has reached the World Cup final, and he will meet Messi again, as Argentina look to win back-to-back World Cups.

That the two would end up by chance in that photo in 2007 is something Monfort described as a surreal coincidence: “The stars aligned."

Monfort has had a long career as a sports photographer since 1991, following Barcelona around the world, but said he's never experienced this level of excitement around any of his photographs before.
