Zoungrana: Pacey with decent Traits, however, with Crossing and Dribbling of 5 and 6 respectively, he's unlikely to ever be good enough
Salim: Strictly left-footed, so unlikely to be able to play out wide on the right
Mohammed: Okayish Pace, but very poor Off The Ball, Dribbling and Crossing, all of which are crucial for a good Wing-Back
Honestly, not the best bunch to choose from, if you're looking for a WB.
Personally, I would look to sign someone better with following characteristics:
Acceleration, Pace, Work Rate > 12
Off The Ball, Dribbling, Crossing > 10
Right Foot > Strong
That would be my starting point, depending on how many options show up.
