It surprise me how often my players get injured lately. If there any tips that helps? I always prepared them with 99% stamina for the match.

20th Jan:
-5:38am friendly match - none injured
-4:30pm League match - 2 injured

21st Jan:
-2:28am Champions League match - one injured
-11:30am friendly match - none injured

22nd Jan:
5:16am League match - one injured

I applied treatment pack on one player to get him available for 5:16am's League match. However, it took just 4 minutes to find out that I have another new member on the injury list. Now I have 6 players injured in my 21 players team, with both main strikers out. Any suggestion?
