Roma midfielder Radja Nainggolan won't rule out leaving this summer.

The Belgium international has been linked with a move to Stamford Bridge, with Chelsea boss Antonio Conte a big fan of the midfielder.

Nainggolan is under contract with the Italian giants until 2020.

"We have just passed the first half of the season and you are talking to me about the transfer market already?" said Nainggolan ahead of tonight's Europa League clash against Lyon.

"I think I am doing well as I have always tried to do.

"Then this [contract extension] is a thing that we have to review in the future.

"Here I am happy, I like to play for this club, but these are things that we will see later on."
