Damage to players ((((

[Antonio Gustavo Hernandez]

b) Don’t train your squad too much: especially if you are playing more than one game per day (like at the beginning of a season), since players are more tired

I have a completely reverse situation. When I train my players with hard and very hard drills before the match, my players never get injured but when I do training sessions for bonuses and use very easy drills they get injured. It happened me today again. In two matches, one of these at home and all my facilities except stadium are at maximum level, two of my players got injured. I also mentioned it in a different thread, I used to think this is a coincidence, but it usually happens to me, not that every day I use very easy drills but nearly always. Of course conditions are usually nearly 90. Am I doing something wrong?

Edit: I have forgotten to mention, I usually train my subs and reserves.
