“The beginning of two legends,” Yamal’s dad, Mounir, wrote alongside the image ahead of Friday’s quarterfinal between Spain and Germany.

In the picture, Yamal is being bathed by his mum, with Messi, who was 20 at the time, leaning in and smiling at the baby who has gone on to star for Barça and Spain as a teenager.

The photo was taken at the end of 2007, the year Yamal was born, by the photographer Joan Monfort and was part of a solidarity calendar put together by the Catalan newspaper Diario Sport. — Marsden
