Asian Football Confederation president Mohamed bin Hammam says is refusing to reveal until Friday whether he will challenge Sepp Blatter for the FIFA presidency.

Bin Hammam told reporters to wait for a scheduled news conference at the confederation’s Malaysian headquarters.

The 61-year-old Qatari has served on FIFA’s executive committee since 1996. Blatter has been FIFA president since 1998 and is up for re-election 1 June for a fourth four-year term.

Journalists gathered at the AFC’s office yesterday, but Bin Hammam focused on an agreement with Premier League club Chelsea on football development.

He laughed when asked about the FIFA presidency, saying, “I know this doesn’t satisfy your curiosity, but I promise on Friday, there will be something.”
