Chelsea have agreed a deal to sign Roma defender Emerson Palmieri, according to a source close to the Serie A club.
Reports state that the Blues will pay an initial £17.6m for the 23-year-old Brazil-born left-back.
Palmieri, who had a season on loan at Palermo during 2014-15, signed for Roma from Santos in December 2016.
He missed the first three months of this season with a knee injury and has made only two appearances for the club, currently fifth in the top flight.
The Blues were also linked with a move for Roma's former Manchester City striker Edin Dzeko.
England midfielder Ross Barkley is Chelsea's only January signing to date, joining the Premier League champions from Everton for £15m.
