Chelsea have completed the signing of defender Emerson Palmieri from Roma.

The Blues needed cover at left-back for Marcos Alonso, having allowed Kenedy to join Premier League rivals Newcastle on loan until the end of the season.

Palmieri, 23, has committed to a four-and-a-half-year deal with the Premier League club.

He told Chelsea’s official website: “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.

“I came here because it’s a great team with a great history. Today I am realising one of my dreams to pull on the shirt of such a great club.”

Former Brazil under-17 international Palmieri, who has since switched international allegiances to Italy, has been restricted to just two appearances in all competitions for Serie A club Roma this season following a serious knee injury.

As such, the defender will be eligible to play for Chelsea in the upcoming Champions League tie against Barcelona.

Chelsea director Marina Granovskaia said: “Emerson 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.”
