Obama keeps Cameron and Merkel under control.
David Cameron watched Chelsea's dramatic penalty shoot-out triumph over Bayern Munich alongside German chancellor Angela Merkel.
The pair saw the final moments of the European Champions League final played out on television together with other world leaders attending the G8 summit at Camp David.
As the drama approached its nail-biting climax Barack Obama was said to have diplomatically positioned himself between them as "referee".
The result provided a measure of revenge for the Prime Minister who was watching alongside Mrs Merkel when England were unceremoniously dumped out of the World Cup by Germany while the two leaders were attending a G20 summit in Toronto.
