According to the Guardian, AS Roma have rejected a £23 million bid (plus plus performance-based bonuses) from Chelsea for Radja Nainggolan. It's believed that Nainggolan is one of incoming manager Antonio Conte's top transfer targets for the summer.
Roma's price tag for Nainggolan is rumoured to be £32 million, although club president James Pallotta reinforced his wish to keep the Chelsea target along with his midfielder companion Miralem Pjanic, who's also been sought after by other big clubs such as Bayern Munich.
"I have already said that we will not sell Pjanic and Nainggolan. I would like to see them continue playing for Roma."

The Guardian also reports that Conte wants to bring another Roma player to Chelsea in Greek defender Kostas Manolas, although there are complications in regards to the player's rights between his current club and his former club Olympiakos, which could be a major stumbling block in a potential move for him this summer.
While there's still plenty of time until the summer transfer window opens on July 1st, Chelsea should be making plenty of advances and lining up key moves well ahead of that date. Hopefully we'll be hearing good news soon.
