Emerson played the full-match as Chelsea beat Tottenham on penalties in the semi-final of the Carabao Cup.
The Brazilian full-back impressed for the Blues, with Marcos Alonso being rested by Sarri.
Emerson has scored the one goal this season, as well as providing one assist in 12 appearances this season.
"Emerson will stay with us, for sure," the Chelsea boss told the club's official website. "He's very important. He's improving.
"Sometimes I had a little problem to put him in because we are not a very physical team so when we play with three little players in the same match, set-pieces could be a problem, but not for another reason.
"I'm very happy with him. He's improving and he's a very good player."
