When it comes to World Cup ads, the bar has already been set pretty high, but this ad from Chile is in a class of its own. 

Bear with us on this one, as it's in Spanish, but this ad for the Chilean national team will make the hairs on the back of your neck stand up. Chile go into this World Cup as a bit of a dark horse with some quality players like Alexis Sanchez and Arturo Vidal, and as their sponsor, the Bank of Chile wanted to put together an ad that would get the country behind them and give the team a bit of a lift. The have accomplished that, and more, with this powerful message from the 33 miners who were trapped for nearly 70 days underground in 'Camp Hope' back in 2010. 

Mario Sepulveda is the ringleader here, recording his message to the team that should give them more than enough motivation to leave absolutely everything out on the pitch. Here's a translation of what he says: 

"In this place, we were trapped for 70 days underground. It was there that we had to prove what we were made of. We knew that outside, there were millions of Chileans who believed in us, and this land, this soil bore witness to all of that.

For that reason, we’re taking this soil to the pitch where our national team trains, to fill them with hope and courage. That way, we can show the world that for a Chilean, nothing is impossible! Spain, difficult? Holland, difficult? We’re not afraid of the group of death, death doesn’t matter to us, because we have already defeated it!"

Spine-tingling stuff...
