Cagliari president Tommaso Giulini has opened the door to re-signing Radja Nainggolan from Inter Milan.

Nainggolan spent last season on-loan in Sardinia.

“The situation is even more complicated compared to this summer, because we don't have the revenue from ticket sales," confessed Giulini on Radiolina.

“However, if Inter want to talk about it, I remain convinced Radja could give us a real helping hand.
