Cagliari have completed the signing of Inter Milan midfielder Radja Nainggolan.

Nainggolan spent 2019-20 on loan at the Casteddu and has now signed for a third stint in Sardinia.

“Cagliari Calcio are pleased to announce that they have acquired the right to the sports services of the player Radja Nainggolan, who moved from Inter on loan until the end of the season," the club wrote on their official website.

“Like a long love story, tinged with red and blue: Cagliari and Nainggolan are once again together.

“The little boy who became a man and a footballer on the island, who left to take flight and rise to an absolute champion level, has always carried the Sardinian flag with him, the Quattro Mori tattooed in his heart."
