Depends on what style suits you, if you like possession or counter attacks, this year formations matter a lot more than previous years. I'm playing so far with 433(3), nice for fast attacking and counters, specially when you set wingers to stay wide and behind defence. And yes, Dybala is so great this year, only thing he lacks imo is heading.
first of all if I'm not allowed to post this then I'm sorry the mods can delete this.
okay so, in fifa 16 i built a serie a squad (4-4-1-1) with dybala pereyera etc as they were kinda op and cheap and i absolutely loved that squad
but now in fifa 17 the game's so different for me, e.g. slow, hard to execute skill moves and through balls are lesser op. any suggestions on what type of squad to go for? my budget is 340k ( squad building challenge :D ) sometimes there are cheap players who are really good but i don't know who to go for.
