Tactics and football have changed. We have gone from every team being relatively equal to some teams being very wealthy and elite. High wages, high expectation. We are, very fortunately, among them. Other teams have now developed tactics to counter the elite, just pack the box and defend and hope for a breakaway or free kick. It's effective. The elite teams need to develop tactics to counteract those tactics. The elite teams that do so will be the most successful. i.e Arsenal have "noticed" that elite teams tend to get more free kicks, throw ins and corners and have adjusted their tactics to make the most of that advantage. We need to innovate and innovate differently every game, we are just too predictable. Most of us know what we are going to do, bring some chaos into the equation, shock us, shock the opposition.
