In the world of football and in all sports in general, we have seen all types of celebrations: some curious, others more fun and others strange.
But we've seen few as 'brave' as Lionel Messi's after he scored Barcelona's second goal in their 3-0 win over Sevilla at Camp Nou on Wednesday.
After scoring, Messi made his way to the cameras at the ground and with his hand made a gesture by drawing two stripes across his face, which is the sign for fight.
The significance is that he was identifying with the 'most brave' campaign which is fighting against cancer in children.
The final objective is to raise the money needed to build the biggest hospital in Europe in Barcelona for children with cancer. They need 30 million euros.
The campaign has the support of the Hospital Sant Joan de Déu, the Fundación Privada Leo Messi, the Fundació FC Barcelona and IESE.
