#1 Harry Winks (Tottenham Hotspur)
During England's recent 3-2 win over Spain, Tottenham's Harry Winks proved he has the potential to compete against world-class midfield counterparts. A very dynamic player who excels at connecting the midfield to attacking areas from deep, he might be precisely the type of figure this Barcelona side needs - someone intelligent, self-assured and aggressive in the right sense.
An excellent passer of the ball and a clever dribbler, he is also press resistant and that makes him perfect for Barcelona's playing style. If he continues progressing at this rate, Spurs will find themselves another talented youngster who is wanted by clubs across Europe.
Barca should consider signing him, to avoid the mistake they made by passing up the opportunity for Luka Modric in the past. He has since flourished at rivals Real Madrid - there's no reason why the Spanish playing style will not work for Winks and allow him to excel too.
