Football fans must be able to drink beer at World Cup venues, according to Fifa. Brazil, which is due to host the tournament in 2014, currently has a ban on drinking booze at football games.
The world governing body has been pushing to make the sale of alcohol within the 12 venues non-negotiable for the tournament's hosts, with Fifa General Secretary Jerome Valcke emphasising that the right to sell beer is an integral part of the World Cup experience.
The brewer Budweiser is one of the tournament's main sponsors.
Fifa's insistence is at odds with the law in Brazil, which banned the sale of booze at football grounds in 2003 after escalating violence.
The Brazilian Congress is currently trying to pass World Cup legislation, however opposition is coming from the country's health minister Alexandre Padilha, stalling the bill.
According to the BBC, Fifa and the Brazilian government have also clashed over cut-price tickets for students and the elderly. There is also concern that the tournament's sponsor's trademarks will not be protected.
Valcke is currently on a tour of Brazil, visiting the stadiums to be used during the competition. At a press conference, he reiterated the importance of a change in the law.
"Alcoholic drinks are part of the Fifa World Cup, so we're going to have them. Excuse me if I sound a bit arrogant but that's something we won't negotiate.
"The fact that we have the right to sell beer has to be a part of the law."
"We lost a lot of time and we were not able to discuss with people in charge that are willing to make a decision," he said.
