Good article and thanks for the link.
My first thoughts.
1. According to this report we seem to play 'proper' zonal defence, i.e. basically as a unit to follow the ball, instead of following(marking) the opposition's players. It might sound very simple, but needs training and understanding. Furthermore the zonal system has given it's name to a little known player. Everybody has heard about the star player and his magics with the ball. Because of the huge demands on understanding the game and movement without possession, fans of the zonal system often talk about the 'best player without the ball'. But I guess in English he's already known as the 'unsung hero'. I think it was Tony Book who said that he smiled when somebody in football said they were trying something new. Because it has all been done before.
2. The attacking play with strikers putting pressure on the opponents. Statistically when winning the ball in the other's half, a lot of goals are scored. Malcolm Allison observed this and called it 'break down'. City won trophies. But the term has since then been long forgotten.
Norway's national team used both these tactics during their succesfull 90's. It was 'new' again then, to most people, and Norway remain the only nation Brazil has never beaten in football (I should add it's only been three games, so it's rather limited as a statistical material!). But based on talent it never should have been a contest. At their heights in the -98 world cup, Norway beat Brazil and got through to the knock-out stages. There they we're knocked out by somebody that had seen it all before. Italy. Money we've got. If Mancini can combine both talent and tactics....then we are in for a few good years!
