Better choosing better formations for VSA like 4-3-3 attack, 3-5-2 and 4-3-3 if you want better defence, you must shoot with fitness shot instead of other shooting things, ST and RW and LB and RB and LW and CM and LM and RM and CAM should be high in attack, the CDM and CB and RB and LB should be high in defence and the gk must be tall (the height is the glitch in GKs), train well the players and choose the best skill points by seeing the tutorial on youtube (to know what is the best skill point for each position), the attack like RW and LW and CAM, and CM and ST and RM and LM should be having 5 star weak foot. If still have these problems and you have a high division, that's suppose to be a cheating because some players use the auto goal cheating by scoring 17 goals sometimes and don't let you win.
