The European Championship has been played every four years since 1960, but the tournament looks much different now to how it did 64 years ago.
In 1960, 17 teams entered the competition but the finals were whittled down to just four teams: France, Yugoslavia, Soviet Union and Czechoslovakia.
And for 20 years, that is how it stayed until a decision was made to double the amount of competing teams to eight.
Following triumphs for West Germany (1980), France (1984), Netherlands (1988) and Denmark (1992), the field doubled again to 16.
And with the quality of European football continuing to improve at an exponential rate, the demand for a 24-team tournament grew and was finally passed a few months after the 2008 Championship.
This will be the fourth Euros played with 24 teams and, despite calls to increase to 32 teams, that is how it will stay for the foreseeable future after UEFA confirmed last year that ‘no change has been proposed for the UEFA EURO final tournament”.
