UEFA president Michel Platini believes Euro 2020 could be held in as many as 12 or 13 cities across Europe.
Platini presented the idea at a press conference on Saturday and claimed that the proposal had the support of most of UEFA’s executive committee.
Turkey were the first to announce that they would be bid for the tournament, with joint bids between Wales, Scotland and the Republic of Ireland and later Azerbaijan and Georgia also confirmed.
The hosts were due to be announced in late 2013 or early 2014 but Platini has revealed that a decision on his new plan will be made in January or February.
The proposal is likely to generate controversy as it would theoretically vastly increase the distances between stadiums and therefore the costs of attending the tournament for fans.
If Wales, Scotland and the Republic of Ireland were to land the tournament, it would be the first time three countries have joint-hosted a European Championship but Platini’s plan would dramatically change the format of the competition.
There will already be a new look to Euro 2016, with 24 teams set to compete in France for the first time.
Initially a four-team tournament in 1960, Europe’s international football showpiece currently has 16 teams.
