Radja Nainggolan cannot guarantee staying with AS Roma.

The midfielder is co-owned by Cagliari.

"Will I stay at Roma?" Nainggolan considered, as he spoke to Gazzetta dello Sport.

"At the moment there's a 50 per cent chance. However, I'm not worried as there's still time. Roma and Cagliari have to find an agreement.

"I'm 100 per cent focused on Roma, it's a great club, a great team and a beautiful city to live in."
