This is awkward.

Manchester City striker Sergio Aguero has taken a selfie with the king of cool, Prime Minister David Cameron, and his Chinese counterpart, President Xi Jinping.

President Xi is in the UK as part of a state visit to the UK and took a tour around the Etihad campus as part of his trip.

"Thank you for the selfie, President Xi" 感谢能与您自拍，习主席！" wrote Aguero on City's official Twitter feed.

What's worse is that the President is supposed to be an avid Manchester United fan - the derby, of course, takes place this weekend.

Who is Mr Cameron supporting this weekend?

We're not sure. He can't even remember if he's an Aston Villa or West Ham fan.

We're also not so sure how this picture will go down back in Aguero's native Argentina, giving the history with Mr Cameron and a certain set of islands in the South Atlantic...
