'When it comes to Spain-Portugal, the situation is different,' Blatter said, noting the countries shared a 'political unity' and common culture that should prevent a repeat of the problems of 2002.
Blatter had in the past said he will accept a bid by Belgium and the Netherlands, but had refused to say whether Spain and Portugal deserved the same treatment.
Obama said the World Cup would provide a 'boost' for football in the US, according to Blatter. The president even showed off a few footballing moves in the White House Oval Office to make his case.
Obama's skills 'merit a compliment,' Blatter said. The president could even have earned a spot on the US team that lost 5-0 to Mexico in the CONCACAF final Sunday. 'The one who lost yesterday, (Obama) would be good,' Blatter joked.
