I talked about this with friend and it's something that FM misses the most:
More positions in tactic screen
FM has, goalkeeper, sweeper, c.defenders.,fullbacks, defensive midfielders,central mid.,attacking mid.,and strikers,with wingers
There is no place for supporting strikers, and I won't play my supporting striker as attacking midfielder.Where to play bergkamp(while he was playing),or rooney etc...They arent attacking midfielders, and they aren't pure strikers either.
Thats position I miss the most, and just like you made a position for sweeper, you could make it for support strikers, between strikers and attacking midfielders
cheers
