The UEFA boss has written to all of FIFA's 209 member associations
to inform them of his hopes of succeeding SeppBlatter.
MrPlatini, 60, said in the letter: "There are times in life
when you have to take your destiny into your own hands.
"I am at one of those decisive moments, at a juncture in my life
and in events that are shaping the future of FIFA."
MrBlatter is to step down on 26 February next year due to the corruption
allegations which have engulfed the organisation.
The two men used to be close allies but a rift between them
deepened when Mr Blatter broke a promise to leave office in 2015.
MrPlatini chose not to oppose the 79-year-old and he won a fifth
presidential term on May 29.
Four days later, however, Mr Blatter announced his intention to
stand down, with FIFA officials being investigated by both US and Swiss
authorities.
MrPlatini, a former French international, is to stand for the top job at
the encouragement of fellow confederation leaders.
Other possible candidates include former Brazil star Zico and
Argentina legend Diego Maradona, although both lack any experience of
international football administration.
Jordanian Prince Ali bin al Hussein, who took on Mr Blatter in
May's vote, got much of his support from UEFA members and is therefore thought
unlikely to run against MrPlatini next year.
Candidates have until October 26 - exactly four months before the vote -
to come forward.
They must have the confirmed backing of at least five of
FIFA's member nations and be cleared by the world governing body's ethics
committee to be able to stand.
MrPlatini has made increasing calls for reform of the world body in
recent months.
These have been heightened since US authorities charged 14 people -
including
