Argentina's football team stood behind a banner claiming the Falkland Islands belonged to the South American country ahead of a friendly match in Buenos Aires.
The team displayed the message apparently in support of the country's claims over the sovereignty of the islands which are a British Overseas Territory.
Despite diplomatic clashes over the territory since President Cristina Fernandez de Kirchner took power in Argentina in 2007, islanders voted by 1,513 to three in favour of remaining British in a referendum last year.
Prime Minister David Cameron said the result of the ballot "could not have sent a clearer message".
Argentina beat Slovenia 2-0, with goals from Lionel Messi and Ricardo Alvarez.
