Radja Nainggolan of AS Roma in action during the UEFA Europa League Round of 16 match against Fiorentina

Radja Nainggolan is unsure whether he will remain at Roma next season as the Giallorossi continue to negotiate with Cagliari over their share of the Belgium international.

Nainggolan has been a mainstay in Rudi Garcia's midfield this season, making 36 appearances so far but his future remains the subject of much speculation - with Liverpool and Manchester United monitoring the siuation having been linked with a £25m move for the player.

Cagliari and Roma co-own the 26-year-old and the clubs have yet to agree a fee that would release him to the latter, while a number of other clubs have been linked with a move for the Begian international.

Nainggolan told Gazzetta dello Sport: "Will I stay at Roma? 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."

Nainggolan was involved in a challenge with Federico Mattiello earlier this month which saw the Chievo midfielder break his leg but the Roma man has been quick to play down any suggestion that he was to blame.

"It was unjust to publish photos of the injury and say that it was my fault. That's not true, it was a mix of circumstances," Nainggolan added. "Even the referee wanted to send off Mattiello and not me.

"I'm sorry for what happened, I immediately sent him a message. I'd have liked to visit him too, but it's not possible as he lives too far away."
