Some sugestions and opinions as i used V2 with full season. but of course you dont have to be agree,) Team is barcelona. yea big one but as you see thewibe got good results with smaller teams too.
1. try to use normal wingers. because in my opinion inside forwards and player who cuts inside decrease the efficiency of tactic. at least use player who use either foot. and also train them to stop cut inside.
2. if you get so many cards tell your players calm down. if they continue substitute them i believe in the impact off side and team talks. if goal doesnt come get creative and push forward etc.
3 full backs are one of the important players in this one. Lots of assist they do
4. Against big sides you may untick the offside trap and maybe decrease the defensive line
5. Striker must be strong one. Both good from air and down. FOr barcelona not messi, suarez messi is SS
6. Some people mention about unefficient SS, but i didnt have the same problem because of messi He doesnt score as often like striker this is all i may say. besides because of the counter strategy as for me a good MC even may play in there,)
7. Against very defencive teams if you cant score you may change atacking mentality but after score change back it counter
again I wanna remind these are my opinion and you dont have to be agree. I watch all matches extended so see so many things.
cheers...
Have you tested a DLF instead of AF?
