The Football Association of Wales are considering approaching their Scottish counterparts over a joint bid to host the 2016 European Championship.
FAW secretary David Collins decided to explore the idea after talks with Welsh sports minister Alun Pugh.
He told BBC Wales: "It's worth investigating if Scotland and Wales could put a bid together.
"We were in discussions with Scotland a few years ago to see if we could put a joint bid together for the Euro 2008 finals but that didn't really go anywhere.
"It's such a major event that we'd need the Welsh Assembly Government and the Cardiff City Council, the Millennium Stadium, the police, the airport, the Welsh Tourist Board, all those people to be on board."
A Scottish Football Association spokeswoman said they had received no formal approach from the Welsh FA.
The SFA and the Football Association of Ireland had a bid to host the 2008 finals rejected.
The FAW is in a stronger position now with Swansea City's 20,000-capacity Liberty Stadium finished and Cardiff City set to build a new 30,000-seat home.
