Michel Platini has confirmed that UEFA will consider leaving FIFA if Sepp Blatter is re-elected as president tomorrow.
UEFA chief Platini was speaking at a press conference in Zurich, where he urged every football association to lend their support to Prince Ali.
As the only opposition to Blatter, Platini stated that a "big majority" of UEFA will back Ali, but admitted that they will consider their future if the Swiss is re-elected.
"If Mr Blatter is the president, UEFA will meet in Berlin to discuss the future of our relations with FIFA. Could UEFA pull out of FIFA? Of course," BBC Sport quotes Platini as saying.
"We will have a meeting and we will talk about all the problems and propositions. I sincerely hope will not pull out, but we will take democratic decisions."
Blatter has refused to resign from his role after FIFA officials were arrested on corruption charges yesterday.
