Siegler is head of FIFA communications
Markus Siegler, 44, has been named FIFA's new Director of Communications. He takes over from Keith Cooper, who was sacked on Tuesday.
Siegler, who previously served as FIFA president Sepp Blatter's communications manager, has been associated with the world governing body for six-and-a-half years and has also worked for UEFA and as an international football consultant.
The move, although not expected quite so soon after the World Cup, was on the cards as part of Blatter's re-organisation of the administration of world soccer's governing body.
Blatter said he would bring "discipline and order" back to FIFA following the fracture at the head of the administration.
That reached its nadir in May, when 11 members of the FIFA executive and the then-FIFA general secretary Michel Zen-Ruffinen filed charges with the Zurich prosecutor, alleging corruption against Blatter.
Zen-Ruffinen was sacked by Blatter two days after the 66-year-old Swiss was re-elected FIFA president at the FIFA Congress in Seoul with an overwhelming majority two days before the World Cup started.
Zen-Ruffinen officially left FIFA on July 4.
Cooper, 55, who had been in charge of communications at FIFA for more than seven years, was given 24 hours to clear his office after being dismissed by acting secretary-general Urs Linsi during a two-minute conversation on Tuesday.
Blatter said just before the end of the World Cup he would spend the next 100 days re-structuring his administration and it is widely expected that a number of other significant changes will be made before the next FIFA Executive Committee meeting in September.
