#4 Konstantinos Manolas
A perpetual Premier League target, Konstantinos Manolas has been silently improving his game and physique at the Italian capital team of AS Roma. Easily one of the best defenders in the Serie A behind the Juventus triumverate, Manolas is one for the future given he's only 24-years-old.
He's quick, heads the ball well and much like Marquinhos can dribble the ball well enough to adapt easily to the kind of style Barcelona demand. His willingness to 'do a Carles Puyol' a la put your head where a leg would go is what has carved him a name for himself in Italy.
Arsenal, Manchester United and Chelsea have been scouting him for years and it finally looks like he could get a move to one of the 'bigger' European clubs this summer but if Barcelona do get him, it'll be a huge boost and could go a long way in determining the future of their defence.
