PARIS - Pressure on FIFA president Gianni Infantino intensified on Tuesday, with opposition emerging from within world football's governing body as well as from external critics over his since-abandoned proposal to open the World Cup to private investment. His remarks followed hot on the heels of an extraordinary internal email to FIFA staff, seen by AFP, in which secretary-general Mattias Grafstrom appeared to distance himself from Infantino on the issue. Previously seen as close to Infantino, Grafstrom describes the fiasco surrounding the plan as "a sad and reproachable series of events". He has reportedly summoned FIFA staff to a crisis meeting in the Moroccan capital as he attempts to cling onto power. Jordanian FA president Prince Ali bin Hussein, twice a FIFA presidential candidate, accused FIFA of "blackmail" in a remarkable statement.
