#3 Mark Cucurella - Eibar (On loan from Barcelona)
Ever since his arrival at La Masia, Cucurella has been one of the most important full-backs for the youth team. A technically gifted left-back and a crossing specialist at the very same time, the 20-year-old could be the most prominent replacement for Jordi Alba.
Right from his crosses to his usage of the width of the pitch, the young Spaniard is often considered as one of the future stars in the world of football and can be the picture perfect replacement for Jordi Alba. Having a similar stature to that of Alba, he won't be any different from the Spaniard.
A product of the Barcelona youth system, the 20-year-old currently plays for Eibar on loan but can be called back to fill in for their current left-back, as he will know the tricks of how to deliver quality football at Camp Nou.
