5. Radja Nainggolan (Inter Milan)
After moving to Inter Milan from AS Roma in the summer transfer window for $ 44.3 million, Radja Nainggolan has had a decent show in the Serie A so far. He has only one goal to his name now but has created some fantastic chances for his team. He bosses the center of midfield and provides solidity and stability to Inter Milan. The Belgian was a vital cog in AS Roma's wheel and now plies his trade for Inter. Tottenham needs to keep him quiet because he can have a hostile effect on the game and change its tempo whenever it suits his team's needs. Nainggolan is no newbie to the big arena of the Champions League and can prove to be the X-factor for Luciano Spalleti's team.
