Iraq or UAE could take Iran’s World Cup finals spot due to Middle East crisis

• Fifa regulations vague on issue of replacing any teams

• Withdrawal would be first since France and India in 1950

Iraq and the United Arab Emirates are viewed as the most likely beneficiaries should Iran withdraw from the World Cup. Fifa's general secretary, Mattias Grafstrom, said on Saturday that our focus is to have a safe World Cup with everybody participating", but the president of the Iranian Football Federation, Mehdi Taj, has raised doubts over his country's participation by saying: After this attack, we cannot be expected to look forward to the World Cup with hope."

Fifa has not commented since Grafstrom spoke and remains determined to ensure the World Cup, which starts on 11 June, goes ahead as planned, but several sources have said that if its hand were forced by Iran's withdrawal the replacement will probably come from the Asian Football Confederation.
