Make sure you enjoy the European Championships over the next three weeks - because after this edition, it will never be the same again.
Euro 2012 will be the last time we see the top 16 nations battle for continental supremacy; by 2016, the finals will be expanded to 24.
The new format means that almost every second country in Europe will qualify, leading to a massive dilution in quality and appeal.
In many ways, the European Championships have often been more appealing - and of a higher quality - than the World Cup. It was the perfect tournament format. There are just 32 games (the World Cup now has 64), almost every game seems vitally important and the final outcomes are often much harder to predict than at Fifa's showpiece event. The Euros have also tended to throw up more surprise champions than the World Cup; look at Greece in 2004 and Denmark's unforgettable triumph in 1992. For the ultimate shock, what about Czechoslovakia beating Germany in 1976, not just for the result but for the fact that the Germans actually lost the penalty shootout, for the first and only time in their history.
Having 24 teams will also means more cumbersome group stages. Sixteen teams will survive to the knockout second round, which means that third place (in a group of four) will be good enough to progress in four of the six groups.
