Just because you have injuries, you don't have to buy tokens. I've always had injuries to players, but I hardly ever use red packs to heal them. Just have a full squad of 22 players, and fill the gaps with reserves.
Exactly! my subs arent brilliant but they can fill in for a few games. Ill only use red packs if its an important game or a star player. Ive three injured just now, all through training i might add but ill not treat them!
