UEFA is set to decree that Euro 2020 host venues must be served by two airports - meaning that Cardiff's Millennium Stadium would face a struggle to be chosen as one of the 13 cities.
With so many cities to be involved the European governing body is anxious to ensure that air travel will not be an issue. That is likely to be something of a headache for Cardiff, and the Welsh FA would have to argue that Bristol or even airports further afield could be used as an alternative for fans.
Dublin and Glasgow are also expected to bid to host group matches at Euro 2020, which for the first time is to be held across Europe instead of in one or two countries. The Football Association is to bid to host the semi-finals and final at Wembley, or group matches and quarter-finals if that is unsuccessful.
