More specifically, the Bolivian President, Evo Morales, was playing a football match against a team of political rivals. When one lunged in with a late tackle and gashed his leg, Evo retaliated with a knee to the groin.
The match swiftly deteriorated into a bad-tempered, foul-filled contest which arguably mirrored the Andean country's combative politics. By the end, the match drawn at 4-4, two players from each side had been sent off, including Cartagena and one of the president's bodyguards.
Makes me nostalgic for the Deputy Prime Minister John Prescott Knock-out (which I thought was well deserved). Evo would thrive in the Stoke City or Arsenal teams.
