Radja Nainggolan (Roma)
The Belgian midfielder joined Roma in January 2014, and has quickly established himself as one of the club’s biggest stars. The 26-year-old has thrived in the absence of the injured Kevin Strootman, but did miss out on selection for his national team squad at the World Cup.
Cagliari own half of the player, and their president Tommaso Giuli has declared him “one of the best midfielders in Europe.” The Mirror describes him as a ‘one-man wrecking-ball’, capable of dominating in the middle of the park.
