The money dispute comes before the Wales v England return match

But the stadium manager has said Wales's World Cup qualifier against England next month is unlikely to be affected.

Paul Sergeant has requested the Football Association of Wales (FAW) pay the costs and warned future matches could be moved unless the cash is paid.

An FAW spokesman said he expected the matter to be sorted out this week.

'Monumental occasion'

The Wales v England World Cup qualifier on 3 September is a sell-out at the 74,000-capacity Millennium Stadium with 6,800 tickets already allocated to travelling English supporters.

Mr Sergeant has written to FAW officials asking for around �250,000 in unpaid costs arising from previous Wales football matches at the Welsh Rugby Union-owned stadium.

Paul Sergeant has called for payment from the FAW by Friday

He has raised the possibility that FAW events there, including Wales' home matches, could be moved or cancelled if the bill issue is not resolved.

He acknowledged that the upcoming Wales v England game would almost certainly not be affected, but told BBC Radio Wales on Wednesday: "We've written on a private basis to the FAW and it is an issue which should be easily resolved before the end of the week.

"We hope we don't have to move it (the England match).

"Everyone's looking forward to it and it is going to be a monumental occasion for the whole of Wales and I'm sure by the end of the week it will all be resolved."

Mr Sergeant added that he hoped the FAW's council would discuss the matter at their meeting in Llandudno on Wednesday.

FAW secretary general David Collins has assured fans there is no danger of the World Cup qualifying match against England being moved from the stadium.

Speaking on BBC Radio Wales, Mr Collins said he expected the affair to be sorted out this week.

Meanwhile, the English FA has admitted contingency plans are being put in place to stage the 2006 FA Cup final at a different venue from Wembley should problems occur in meeting the deadline in the new stadium's construction.

FA officials have been told that work at Wembley is on schedule, which would mean a return to London for the cup final for the first time since 2000.

Since 2001, the showpiece game has been played at the Millennium Stadium and Mr Sergeant said the venue was ready to host the match if needed.

He added: "We'd love to have the FA Cup final back here in Cardiff one more time. My sympathy goes out to Wembley - they've got a lot of work to do.

"Our position at the moment is that we know the date of the final, we'd love it to come to the Millennium Stadium and the FA know we're here and waiting."
