Join the club! i have injuries every day!

What am i doing wrong? Watching videos for red packs that could be the guilty factor

and my 2 favs:
-coming the feeling pain text at 9th min (!!!) without any hard tackling from opponent (!!!)... after the usual 6 day off... -.-
aaaand if i got a hard tackling, coming the 9 day injury! its nonsense

-buying expensive young talent and curioulsy i hit him a normal cardio (!!!!) and the following 2-3 day off
(iam always training in GREEN range!)
