Project Oxford initiative have launched a new tool that allows us to upload photos and delivers a breakdown of eight basic emotions.

When Carlos Tevez signed for West Ham, the tool went berserk detecting every one of the eight emotions. A clear sign he had no idea how to process it.
Jose Mourinho claimed to be the 'happy one' at a press conference just moments after this photo was taken, but it turns out he wasn't as cheerful as he made out.
Thomas Gravesen holds up a Real Madrid shirt beside club President Florentino Perez after signing at the Bernabeu in 2005. And yep, he's 100 % the cat that got the cream.
Lionel Messi won the Golden Ball trophy immediately after being defeated by Germany in the World Cup final at the Maracana. Anger, contempt, sadness, disgust, he felt it all.
And finally, Sergio...tut, tut, tut. When Aguero squished his face against David Cameron and took a selfie, he was feeling almost 100% happy. (Apologies to the President of China Xi Jinping for blocking him out).
