Firstly, I know its a wikipedia article and can be edited...
Apparantly we could be hosting EURO 2020 along with Scotland and ireland, some kind of Celtic alliance rubbish. I read it somewhere a few weeks back so looked on wikipedia just now and it says we have signalled our interest:

Personally I would love it as the final would most likely be in the Millenium and then Welsh football would probably go through the roof.
