When Spain successfully defended their continental crown by thrashing Italy 4-0 in the final of Euro 2012, two years after lifting the World Cup, their place amongst the greatest international teams in football history was secured. La Furia Roja’s golden generation, built around the Barcelona midfield triumvirate of Xavi, Andres Iniesta and Sergio Busquets, have largely remained intact. Immortality beckons in Brazil this summer. Spain’s standing as the greatest international side ever will be beyond dispute should they win an unprecedented fourth consecutive major title and become the first European side to lift the World Cup in South America. To accomplish this, however, Spain, and their rivals will need to perform in sweltering temperatures and stifling humidity. With six of the 12 host cities for the tournament located away from the cooler south-east stretch of Brazil, the 2014 World Cup will be as much a test of stamina and conditioning as skill.
