Blatter: Doubts about 2007 (BenRadford/Allsport)

The Cup is held every two years featuring the champions of each of the six continental confederations that make up world governing body FIFA, plus the World Cup winners and the host nation.

'I can give no guarantee that in 2007 there will be a Confederations Cup or not,' Blatter said on Monday.

Blatter set up the event to try to reduce the power of European clubs and make the game more global, but its future is under a cloud after European ruling body UEFA said last month it would pull out of the tournament after the 2003 event in Germany.

No venue has been chosen for the 2003 Confederations Cup but the 2005 event will be staged in Germany as a dress rehearsal for the 2006 World Cup, just as the 2001 Confederations Cup was staged in South Korea and Japan.

FIFA wants the return of the World Club Championship from 2005 after the collapse of FIFA's long-term marketing partner ISL-ISMM forced the cancellation of the last world club event due to have been played in Spain in August 2001.

Blatter warned that the Confederations Cup after 2007 and the World Club Championship would not be played at the expense of existing FIFA tournaments and its commitment to the development of youth and women's football.

INTERNATIONAL CALENDAR

'We have to see if in the international calendar there is space for both of these competitions, the Confederations Cup and the World Club Championship, because the other competitions cannot be touched,' Blatter said.

He added the Confederations Cup up to 2005 was included in FIFA contracts which expire in 2006.

'When we go to the World Cup in 2010 we will have new contracts for television, for marketing...and it is not yet decided which will be the competitions of FIFA after 2006,' Blatter said.

New South Wales Premier Bob Carr said on Sunday that Australia would consider bidding for the 2007 Confederations Cup.

Carr and Victoria state counterpart Steve Bracks announced at the weekend a surprise Australian bid for the 2014 World Cup.

But by Monday that announcement began to look like an own goal as Soccer Australia squabbled over whether it would be able to launch a bid and organise the event.
