Has he revolutionised football in England? Also if he has, is that positive? Southampton lost to Liverpool last week because they got caught playing out when it was never on. They take points off Liverpool there it works in the favour of City. Burnley went down because they wouldn't change how they play.
It's also pretty standard Spanish football as well. Hot country, start of the season is 30c+, end of the season is 30c+, best way to play is to keep the ball in that heat. Worth remembering Spain won Euro 2008 playing tiki taka, which was a very Spanish way of playing adopted by Luis Aragones and the RFEF (Spanish FA) several years previous, Pep for the 2007/08 season was managing Barça B, so his impact on Spanish football there was negligible. They also won the 2010 World Cup and Euro 2012 playing the same way. The other way to look at it is if he has a long lasting impact. If he did in Germany, they lost their national identity, and had their worst tournament showing since before WW2 recently. Revolutionising something doesn't necessarily mean it's positive. The idea of football is to win games, you do that by scoring more goals than your opponent. How you do that is irrelevant as long as you do it.
