FIFA President Sepp Blatter highlighted the need of 'deep-rooted structural change' at the organisation when he announced his decision to step down.

"For years, we have worked hard to put in place administrative reforms, but it is plain to me that while these must continue, they are not enough," Blatter said in remarks posted on FIFA website.

Blatter announced his decision on the day when it emerged that US authorities investigating corruption believe FIFA secretary general Jerome Valcke was the top official at the organisation behind the payment of USD 10 M to accounts controlled by former FIFA vice-president Jack Warner, who is now under criminal investigation.

Authorities are investigating the transfer of the sum paid on behalf of 2010 World Cup hosts South Africa, which had been unable to pay directly from government funds, DPA noted in its coverage of the news.
