“Markus’s pace and fearlessness fits a need up top for us,” said LeBlanc. “He’s willing to do the work on both sides of the ball and he knows how to finish when he gets the chance. I’ve coached him in the Union organization, so I know his mentality, and I know what it means for him to come home and represent Brooklyn.”

He scored 10 goals in 29 appearances for Rayo Majadahonda’s reserve team, Paracuellos Antamira, in the Spanish fifth tier before being called up to the club’s first team, for whom he made 21 appearances and scored 3 goals in Spain’s third flight.
