Need a Good tactic for Cardiff City
I will always choose the stance that it is more rewarding to create a tactic yourself. If you're looking for a tactic we have a great tactic section here: http://www.fmscout.com/c-tactics15.html
You might not get far with asking for a tactic for a certain team as there are thousands of playable teams in FM and the chance that one FM player have chosen the same team and made the same transfers as you is very low.
Feel free to ask questions in our tactics section. It would be nice to have a good debate in there.
