Torreira netted the winner as Arsenal beat Huddersfield this afternoon at the Emirates.
Arsenal go back above Chelsea and into fourth ahead of their match with Manchester City this afternoon.
Torreira scored a stunning bicycle kick to break the deadlock after 82 minutes.
And Emery reckons he will keep improving.
“His performance is improving, each player with taking confidence, with taking responsibility also, helping each other, every player,” Emery said before the Huddersfield game.
“Lucas Torreira has big qualities, and in his physical condition.
“I want every player to be able to play Sunday-Wednesday-Saturday with a big performance in condition physically, and tactically and technically.
“Lucas Torreira, in this quality, he is very high.”
Torreira joined Arsenal from Sampdoria and has become a big fan favourite already.
He scored in the north London derby and again today.
And Arsenal fans are ready to hand over whatever the 5 ft 5 star wants.
“Give that baby whatever he desires,” one fan tweeted.
“If he desires to live in the Buckingham Palace, then the Queen has to leave with immediate effect!!!! Our season hero!!”
“Thank you once again Lucas Torreira for that wonderful goal,” another said.
“He remains the best thing that happened to Arsenal this season Dear Emery, pls sort out that Ozil’s back spasm asap. His creativity was missed today.”
