I have to say that this tactic works very well on Instant Result. I started as a lower league Danish team and got tired of the non fluently play (cuz of the lack of skills of the players XD) So I started to use IR and I just ran over the entire league. Media pred 4th. And I got easily promoted :)
Okay, Im curious about the IWB's, do they need to be full trained IWB's with reverse foot, left foot on right side and opposite? Or can you ex. normal wingbacks as IWB's?
And one more thing. To understand correctly, you change players to their favourite role if you dont find them good enough for the "original" role in the tac?
