One possible explanation for the Dribbler not showing is the fact that most of time, that special ability is on the wrong player (in the wrong position), hence the situation for dribbling is unlikely. It is something that I have already talked about last year. MCs are usually not dribblers, and dribbling is of little use for them. Dribbling is useful for one-on-one situations where there is space available to exploit. Wingers and STs are usually the ones that should have this special ability, not MCs, but in this game players having AM or ST positions only cannot be assigned this special ability.
This could be a mistake from Nordeus.
