So you a bad manager then. Why are u supposed to be free of injuries? Everyone has chance of having injuries and everyone , well atleast good managers should prepare for them. Some guys use 7man roster, some guys saves some cash for a guy to buy of transfer market(like i always do, and just did because me star player got injuries for 2 weeks, and i wont relegate cause i saved some cash for that occasion if injuries happens). So basicly everyone is playing in similar conditions and if you dont prepare for them its ur fault, it means u worsier manager and in this case u are worth to lose those games and lose a cup run.
