Cagliari are prepared to sell Radja Nainggolan this month.
â€śNainggolan is worth more than â‚¬15m,â€ť Rossoblu sporting director Nicola Salerno told Sport Italia. â€śOnly President Massimo Cellino knows the precise figure.
â€śHowever, it is pointless talking about it right now as there are no negotiations taking place. There is time though.
â€śWe are not interested in any player plus cash deals though. If someone wants Nainggolan then he will cost that much.â€ť
