Speaking at a press conference this morning Chris Coleman has said thanks but no thanks to using the Principality Stadium for future Welsh football matches.
FAW chief executive Jonathan Ford says the 72,500-capacity Principality Stadium is an option, reports BBC Sport
But after Wales' historic run to the Euro 2016 semi-finals, their manager wants to stay at Cardiff City Stadium, which holds 33,000.
"I would imagine we're going to stick to that," Coleman said.
"And we should stick to it.
"We could gamble and go back to the Millennium Stadium. It is a magnificent stadium, we know that, we could get another 20,000 maybe, but we made a choice.
"I'd rather be playing at Cardiff City Stadium where there's 30,000 screaming Taffs breathing down the opposition's neck, and our boys feeding off that."
Wales will start their 2018 World Cup qualifying campaign against Moldova at Cardiff City Stadium on 5 September.
It is understood they could play a friendly match at the Principality Stadium before it hosts the 2017 Champions League final.
Wales last played at the home of Welsh rugby in a 2-0 Euro 2012 qualifier defeat by England in March, 2011.
"We've got both options available to us," said Ford.
"If the demand is there we need to satisfy that demand whether that's at the Cardiff City Stadium or the Principality Stadium. But obviously it's not available to us for every single match."
