Radja Nainggolan could be tempted by a move to Real Madrid.

Nainggolan has been linked for months to a transfer from Roma to Manchester United and Liverpool.

"I believe Nainggolan will stay at Roma, although when you are talking about Real Madrid, things can change," said Nainggolan's agent. "[Roma president James] Pallotta knows that Nainggolan is very important for Roma, and could have many offers for the player. Keep an eye out for Real Madrid."
