Yes, I'm using 4-5-1V at most match depend opponent formation and strength from level 1 to level 5 (now level 6). But this formation look like not working well since end of last season and cause i lose my league title. I'm also lose my cup match yesterday. I also bring in more quality player with SA, set max match price, condition and moral at 9+%. My team also easy to concede goal from corner, even though my defender has aerial SA. Should i change my team formation? Need your input and thanks!
