#2 Ousmane Dembele
The Frenchman might have won the FIFA World Cup over the summer, but Dembele's career has failed to flourish ever since he joined Barcelona last season. However, he is in contention because he has already played in the right wing in a couple of games this season, against Athletic Bilbao and Seville.
Dembele has scored 5 goals from 11 appearances so far this season, but all of his goals have come while starting from the left attacking position. Nevertheless, the youngster is equally adept at playing in the right attacking position and has the necessary speed and trickery to cause the opposition enough trouble on his day. Perhaps his lack of consistency would be the only concern, but Dembele gives Barcelona a great option ahead of the El Clasico.
Against Real Madrid, Dembele could get a run in if Valverde decides to go all out for the win at Nou Camp, and the Frenchman has the ability to cause the Real Madrid defence some serious trouble.
