How old will those players be and why there are some undesirable (or lets say, less logical) special abilities as possibilities? Defender with free-kick ability, and MC or AMC with corner special ability? And that dribbler special ability, does it even work? I bought two expensive recommended players that had the dribbler special ability, but it does not seem to do anything.
I have tried them once or twice now, about 22 yrs and you get a bonus (secondary) position. Really good fast learners, but they don't guarantee victory.
