Barcelona B coach Gerard Lopez is demanding more from Marlon Santos.

The young Brazilian defender was left on the bench against Hercules at the Mini Estadi.

Sport says the reason is that the coach was not happy with Marlon against Atletico Saguntino and wants more from him.

Lopez is working with him individually to improve his performance, particularly in the creation of play.

Marlon has been involved with Barca's senior team at Champions League level this season.
