Football Association of Ireland (FAI) chief executive John Delaney admits he is not surprised by Sepp Blatter's decision to resign as FIFA president.

The 79-year old made the announcement on Tuesday, just four days after gaining re-election as the chief of world football's governing body.

In the wake of the shock decision, FAI boss Delaney said: "It's a good, even a great day for world football.

"Hardly surprising, maybe people are surprised that it took only four days since he was elected.

"But there was a momentum against him, be it the 73 countries who voted against him, be it the supporters, be it a FBI investigation, be it David Cameron, be it the sponsors.

"I mean the whole world wanted a change with FIFA at the highest level, they wanted Blatter to go and the whole world wanted a change of culture at FIFA."
