7) David Luiz (Paris Saint-Germain)
Although mostly used as a defender at Chelsea, David Luiz looks likely to be moved into midfield after showing more ability in bringing the ball forward, linking play and scoring the occasional wonder-goal than at doing his defensive duties to the required standard. The Brazilian had a nightmare World Cup for his country, but he could revive his career with a big move to Paris Saint-Germain, if he is given the chance to operate further up the pitch.
