I had played with your tactic 3 years with Leverkusen, buying only young germans (Bell, Kopplin, Volland, Geis, Pannewitz, etc.) and Sigurdsson & Sigtorsson! My results are:
3 Title in Bundesliga, 1 German Cup, 1 1/4 final, 1 final and 1 1/2 final in Champions League.
In the second year I have been unbeaten in both CL and Bundesliga except in the CL final against Liverpool.
For the Word Cup 2010, eleven player of my team are making the German National Team (Leno, Reinartz, Bell, Wollscheid, Marin, Geis, Sam, Kiessling, Schürrle, Kopplin and Volland)!
The team play a really great soccer with a lot of shoots and CCC. I also conced very few goals. I have beat teams like Bayern Munich and Dortmund 5-0 three or four times!
This tactic is not about the corner. Yes you score on corner but usually, you get that corner after a great action and shoot! With all the shoots, you have a good amount of corner in a game so it's normal that you score sometimes. In my last 50 games, my team scores 127 goals and only 15 were corner (12%). It's not that much. Before that, I tried JP Woody Wenger's style 442 tactic and THAT was just about corner goals!!!
So, thanks for your tactic! I really enjoy it and I'm looking forward your next version!
