Indonesian billionaire Erick Thohir is being asked in his home country about Inter Milan's move for Cagliari midfielder Radja Nainggolan.

Italian media sources say Thohir could complete the purchase of a controlling stake in Inter before September 1.

And given Nainggolan's Indonesian roots, Thohir is being asked about his signing.

"Nainggolan? I'm not the owner, but I think a better view of the situation would be offered by the coach."
