Chelsea signing Diego Moreira has been dubbed a "street footballer".
Moreira joined Chelsea on Saturday from Benfica.
Luis Castro, who coached the Benfica B team last season, told Maisfutebol: He has improved a lot. He has this street football style, but it is increasingly productive.
He is managing to reconcile being entertaining, because he brings spectacle to the game, with better statistics. And he has a very particular characteristic, which is not normal for a player of his talents, which is the defensive component.
He's a defensive animal and I don't see many wingers worldwide with Diego Moreira's defensive commitment."
