I have been at PSG for 5 years and with great success, all of a sudden in my 6th season my tactic 4-1-1-3-1 has stopped me from dominating games like i used to. I cant use my current backup because all my players play in roles that dont match. What should i do?
Same thing happens to me, though I wish they had gone further with it, and made opposition teams start to copy your formation and tactics if you're successful. That's one of the ways I think the game could be made massively more realistic.
What you need to do is become more flexible, I've written an article on this site which might help about how I have 40 tactics prepared for my team, click here to see it. I tend to use one or two tactics the majority of the time, with the odd different one for specific games. After a few years, the main tactics became less successful, so now I've shifted to a different formation, using the techniques I described in the article the team was already prepared for the change, so I've carried on winning without any problems.
