this is the complete opposite of sergi
Well, Semedo can beat opponents on the dribble one on one, but then after that he losses the ball or has to make a pass that does nothing to advance the offense. He never accomplishes anything good when he goes too far forward or to the goal. No matter who else is playing on his side of the field, he just sucks trying to go into the corner or to the goal. This is not the fault of the formation or his teammates or his coach.
His only chance to be able to continue on this this team is to just not go too far forward or too far into the middle. Ever. Just stay back, receive emergency passes as an outlet, be more ready to defend than a real Barca fullback. With Semedo on the field, Barca can be less symmetrical. Jordi can do his fantastic work in the offense on the left, Semedo can hang back. Semedo's teammates are already making this happen by refusing to pass to him. His teammates are not stupid. They also did not like to pass to Douglas, or to Aleix Vidal, or to Deulofeu, or to Paco, or to Montoya, and maybe not to Munir.
