The Uruguayan scored the only goal of the game to stretch Gunners’ unbeaten run to 21 games in all competitions.
Matteo Guendouzi’s ball into the box found Pierre-Emerick Aubameyang at the far post.
Aubameyang has been in superb form in front goof goal himself this season but turned provider as he chipped an inviting ball to the unmarked Torrerira who was lurking just inside the six-yard box.
And the 22-year-old summer signing launched himself into the air before dispatching a scissor kick past the helpless Jonas Lossl.
Here is a selection of the tweets aimed at the Gunners midfielder.
“Marry me Lucas Torreira.”
“Lucas Torreira plz (sic) marry me.”
“Lucas Torreira will you marry me (sic)”
“I do want Luca Torreira to marry me.”
“LUCAS TORRERIRA MARRY ME”
“Lucas Torreira marry me you beautiful b*****d.”
“Lucas Torreira should marry me. That is all.”
Torreira has shone since signing for Arsenal from Sampdoria for £22million in July.
He now has two goals in his last three Premier League games, including the crucial strike that wrapped up the 4-2 victory over arch rivals Tottenham in last weekend’s north London derby.
