On Friday, Chinese president Xi Jinping spent the final day of his four-day visit in Manchester and spent some time at the City of Manchester Stadium. So Man City striker Sergio Aguero took a selfie with Xi and the PM.
.@aguerosergiokun: "Thank you for the selfie, President Xi" 感谢能与您自拍，习主席！#CFAStateVisit
People are pretty confused.
This a real selfie?
Others are just extremely disappointed.
MAKE IT STOP
Before long, people started commenting on what the odd picture might represent.
New Top Gear line-up rather unexpected.
Such as the new "Hangover" movie.
Hangover 4 looks rubbish
It was suggested that David Cameron's eagerness to get into that photo might suggest that he's backing Manchester City.
A red and two blues in Derby week...
Speaking of Cameron's face...
when your friend leans in too much for a selfie
There's also a very simple answer for those of you wondering why Xi looks so unimpressed. He supports the other team in Manchester.
The Chinese president is a big fan of @ManUtd – so David Cameron took him to meet @AgueroSergioKun. 😂😂😂😂😂😂
