LONDON — Chelsea finally signed a back-up for Marcos Alonso at left wing back by bringing in Emerson Palmieri from Roma on the next-to-last day of the January transfer window.

Palmieri, a former Brazil Under-17 international who has since switched his international allegiance to Italy, has been restricted to just two appearances in all competitions this season following a serious knee injury.

“English football is something I have been watching since I was 15 years old,” he said Tuesday. “It is a really beautiful game over here, but it is going to be even more beautiful to play it.”

Alonso has been Chelsea’s only senior left wing back this season after manager Antonio Conte missed out on signing any cover last summer.

Everton striker Sandro Ramirez will join Sevilla on loan for the rest of the season subject to a medical, while Leicester forward Ahmed Musa joined former club CSKA Moscow on loan for the rest of the season.

Watford signed Belgium Under-21 winger Dodi Lukebakio on a 4 1/2-year deal and allowed Mauro Zarate to join Velez Sarsfield on loan until the end of the season.
