Sepp Blatter was warned from within FIFA on Sunday not to attempt to backtrack on his pledge to quit as president. Domenico Scala, who is overseeing the presidential election, said that a leadership change is an essential component of the far-reaching reforms required to overhaul FIFA amid deepening criminal investigations into soccer corruption. Scala’s blunt comments came after Swiss newspaper Schweiz am Sonntag, citing unnamed sources, reported that Blatter is considering trying to retain the presidency after receiving support from Africa and Asia.
