FUT Champs too difficult/ball on a string

fut champs is very difficult I  cannot even win 1 game

how can the opposition player tackle 1 player fall over on his back

then the ball falls to my other striker

then the opposition player manages to get up off the floor

and tackle my other striker who is 6 steps away. makes no sense

Matchmaking is not good I know fut champs is intense but I always play

people who are extremely extremely desperate to win

they will do everything twist turn twist turn wiggle wiggle and shoot then its a goal.
