"I have great confidence in UEFA," Nicolae said. "UEFA proved time and time again that they know what to do and they did the right thing. With FIFA I don't have that. Blatter is erratic and I think it's time for him to resign."
On Friday, the Greek football federation banned Giorgos Katidis for five club matches and fined the AEK Athens midfielder 1,000 euros ($1,300) following his Nazi-style goal celebration last month.
The ban is largely symbolic as the 20-year-old had already been suspended for the rest of this season by his club, and the federation had earlier banned him for life from representing his country.
Also on Friday, FIFA confirmed that Brazil will not be completely ready to host June's Confederations Cup -- a precursor event to next year's World Cup in the South American country.
"It will be a fantastic tournament -- but not all operational arrangements will be 100%" secretary general Jerome Valcke wrote in his monthly column on the FIFA website, on the same day of the inauguration of the third of the tournament's six host stadiums at the Arena Fonte Nova in Salvador.
He said work on venues in Recife, Brasilia and Rio de Janeiro (the redeveloped Maracana stadium) is due to be completed by the end of this month. There will be 12 grounds used at the 32-team World Cup, which will host 64 matches -- four times that of the eight-nation Confederations Cup.
"It is impossible to expect this to happen in the shortened preparation time -- in most cases, less than two months instead of the scheduled six -- due to the compromises we made with the cities," Valcke said.
"I want to reiterate: this will be impossible to repeat for the FIFA World Cup, and has been acknowledged by the federal government and LOC. The deadline for the FIFA World Cup stadiums delivery stands firm as December 2013. There will be no compromise."
