Jonathan Ford: FAW put Euro 2016 ahead of short term gain
Football Association of Wales (FAW) chief executive Jonathan Ford has "not ruled out" the national team returning to the Millennium Stadium.
Wales' face Belgium on 12 June at a sold-out Cardiff City Stadium.
Despite the potential to sell more tickets Ford says matches will remain there for now.
"Long term financial gains of qualifying will be considerably more than shorter term gains of playing at the Millennium Stadium," he said.
"We've not ruled the Millennium Stadium out in the longer term."
The Millennium Stadium has a capacity of 74,000 compared with 33,000 at the Cardiff City Stadium.
However, Wales will play their three remaining home qualifying matches for Euro 2016 at the smaller stadium, starting with Group B leaders Belgium.

|12 Jun 2015: Belgium (h)||10 Oct 2015: Bosnia-Hercegovina (a)|
|3 Sep 2015: Cyprus (a)||13 Oct 2015: Andorra (h)|
|6 Sep 2015: Israel (h)|
Both teams are unbeaten, with the Belgians topping the pool on goal difference.
The FAW made a loss in the last financial year after tax of £28,935 despite increasing its annual income by 10% from £7.9m to £8.7m.
When the figures were revealed Ford said the organisation did not need to "generate any profit", but that any money made would be ploughed "back into football."
He says everything is focused on giving the Wales squad, who want to play their home matches at Cardiff City Stadium, the best chance of reaching the finals in France.
"We've got a great team. We've got a got Chris Coleman in place and he's doing a great job for us," said Ford.
"Ultimately we want to ensure that we give them [Wales] every possibility of reaching the long term goal [qualifying for a major tournament]," said Ford.
