The format of the final tournament will consist of six groups of four teams, followed by a round of 16, quarter-finals, semi-finals and final. The top two from each group would qualify in addition to the four best third-ranked sides, the same system as was applied in the World Cups from 1986 to 1994. This format would generate a total of 51 to 52 games, compared with 31 now, to be played over a period of 29 to 31 days. UEFA's general secretary Gianni Infantino said that the new format was "not ideal" and that UEFA was not sure of the detail of the format.
I'm a little shaky about the ''four best third-ranked sides'', oh man this should make for fun tie-breakers. So I took a peak back at Euro Cup 2012 Qualifying just to see which sides missed out
