5* weak foot and good agility is all I need in a good attacking midfielder.
Weak foot ability is useful in the middle, certainly...but then there's also the option of buying one player and working out his stronger side and using that to your advantage yourself. Agility is good for quick dribbling sure, but it becomes even more useful with skill moves to use because you can rack them off quickly. In conjunction with good ball control and dribbling you'll have a masterpiece.
If it were my career mode this is the ideal team I'd try to form at the start of the game
In 4-1-4-1
GK: Kapino
RB: Clyne
CBs: Okore and Kongolo (Ake if I found the time to build him up)
LB: Melgarejo/Willems/Shaw
CDM: Junior Malanda
RM: Bakkali (Pablo Sarabia or Kelvin, Vadillo if I were confident, at first because Bakkali takes time to raise)
CMs: VILHENA (87 potential!!! (and good at pretty much everything) If only he were still 4*

) plus Paredes or Oliver Torres. Jonathan Williams if I just want to be fast
LM: Deulofeu above all (he has been switched to a RW for no real reason, so I'm running him in the position he always has been), though there are a ton of good people at this position (Pizzi, Lucas Piazon, Mackay-Steven, definitely Boetius, Bruma, Edison Flores, Bernat at a push...
you can use Jese and Fischer if you want, but I won't)
ST: Wellington Nem if I were being very, very cheap, but more likely someone like Matej "Mr Otter" Vydra or Romarinho (he is the same as Wellington Nem really isn't he...

) Maybe Chelsea's new Islam Feruz lad?
