Chelsea have announced the arrival of Roma full-back Emerson Palmieri.
Emerson is still working his way back to full fitness after a serious knee injury that scuppered the Brazilian-born defender's chances of making an international bow for Italy in May last year.
He is believed to have cost an initial £17.5million and has signed a four-and-a-half-year contract.
The 23-year-old will provide competition for incumbent left-back Marcus Alonso following a move that was facilitated by Kenedy's loan exit to Newcastle United.
Negotiations over a potential double-signing involving Roma striker Edin Dzeko stalled and Chelsea had to settle for a deal that does not include the former Manchester City target man.
Emerson, who began his career at Santos in Brazil, arrived in Serie A on loan at Palermo in August 2014. He joined Roma the following season but was only signed permanently in December 2016.
"I came here because it’s a great team with a great history," the defender told the club's official website. "Today I am realising one of my dreams to pull on the shirt of such a great club.
"English football is something I have been watching since I was 15 years old. It is a really beautiful game over here but it is going to be even more beautiful to play it."
Chelsea director Marina Granovskaia added: "We are delighted to welcome Emerson to the club. He is a young and talented player who strengthens the squad and will provide excellent competition for places as we pursue success in three different competitions."
