Small squads can drain green packs but reds are the most difficult aspect.

My situation is a bit more extreme atm than usual but I have 4 playable subs (I'd usually have at least 6). I'm currently running with 1 GK, 6 DCs (4 with DL/DR and 2 with DMC), 3 MCs, 3 AM*/M* wingers and 2 STs.

I don't find it difficult to leave players out when necessary or change formations but a rush on injuries can be a big problem.
