Ok sometimes there can be players that r hurt but not that too many, a lot of ppl whining nowadays about that.
Dont tell that "its the same in real life" argument.

let u say them,

There is a maximum of 4 injured players at the same time. If you have 4 injured players in your roster, you won't get a new injured player.

Maybe you should use this knowledge

i give free leson for 11x11 just ask on pm
im like litl murinho haahahahah

So 4 players get injured, I heal them, and they get injured again? In real football, not more than 2-3 players get injured in the whole season!
