4) Juan Cuadrado (Fiorentina)
One of the best wingers in Serie A in 2013/14, Juan Cuadrado has been in the headlines recently after his fine performances for Colombia at the 2014 World Cup, where he shone as one of the stand-out players of the tournament alongside his international team-mate James Rodriguez. Juventus have been one of many clubs linked with him in recent times, along with other big names such as Arsenal, Manchester United and Barcelona. Cuadrado certainly looks ready to make the step up to a bigger club this summer, and would fit in well in Turin where he could really establish himself as one of the best players in Europe.
