Not having a go, but how would you describe a player who has the ability to manipulate the ball in a very useful fashion be it for shooting, passing, set pieces and is well, technically gifted?
Why they want to loan him out instead of keeping him for Barca B I don't know. My best guess would be they have lots of striker for their second team and because he is in the middle of first team fringes and B team player they want to loan him out.
Mate at the club who says he heard whispers about a possible move. According to him Barca have had interest from lots of clubs but they want one who can offer 1st team football every game but will keep him drilled and have good technical quality and pass the ball.
