Hey,
Thanks for downloading my tiki-taka tactic.
I know the tiki-taka is the way Barcelona normally plays and that you should think they would be excellent from the start in FM13. But it's important to understand that the tactic will not fully work (or see the potential off) until the
tactic familiarity levels are 100% (or competent)
As a general rule I will say 10-20 games will be enough to reach a good level of familiarity for your players.
But if you have bought "a lot" of players the team cohesion and their understand between each other will decrease which also takes longer time to get success.
I really needs to know more about what's wrong (aka what's not working for you) before I can answer you what's wrong.
Hopefully you've read my guide on how to win possession and the importance of closing down, showing onto specific/weaker foot) and tackle specific players in key positions (often DC, DM and MC's)
I know I made a personal mistake for some time ago as I uploaded the wrong tactic which have decreased the amount of possession - I'm at the moment working on a improved version of the tactic to make it fit teams who does not have the same PPM's as Lionel Messi (trequartista) and Pedro (AMR) and so on.
Hopefully the new version will increase amount of shots both on target and possession.
I can reveal one version of the tactic used against tougher opponents made me achieved a 4-0 win against Athletic - where they even didn't managed to get a shot on goal and had a passing completion ratio of only 59% in defence
When I decide to release the new version - still testing it - I will announce it here!
