the tactic doesnt no, however if you read the information in the thread it will help you build yourself a tactic using the idea you posted above.
The thread is absolutely fantastic for anyone who wishes to pursue a possession based approach, which in essence is how Barca play
No mate. I saw that game and Villa's job was maintain both centre-backs occupied. So I'll go for Advanced Forward or Poacher. As trequartista he would drop deeper and that's not his purpose. DLF was also a good option but I guess it is not what you want for your recreation..
