AS Roma have announced the signing of Cagliari midfielder Radja Nainggolan. The Giallorossi saw off competition from Juventus and Napoli to land the Belgium international.

Nainggolan moves to Roma for an initial six-month loan, which will earn Cagliari a €3 million fee. Roma can make the deal permanent in June for another €6 million.

Should that happen, Nainggolan will be contracted to 2018 by Roma.
