Twitter user @aloe_vjera posted a series of statistics showing the difference between Arsenal when Torreira is and isn't playing.
He bobbed up again after Hector Bellerin's speculative back heel volley to twice head the ball through and was on hand to turn in the final cross from Pierre-Emerick Aubameyang.
And Arsenal are two points behind, yeah?
It only took Ramsey a matter of seconds to put Arsenal 3-1 up with a sweet finish courtesy of an Aubameyang's assist.
Ramsey's contract with Arsenal expires at the end of the season and the club are not prepared to offer him a new deal.
It has come as a no surprise that this Ramsey's shaky Arsenal situation has caught the eyes Liverpool and Manchester United and with Wales worldwide will be available for free in the transfer market, it could be a bumper opportunity for the Merseyside and Manchester club to grab the skilful midfielder at the cost of nothing.
Yet, even if Ramsey does leave, Emery is clearly not short of midfield options, with Alex Iwobi impressing before being replaced by the Welshman and Germany's Mesut Ozil to come back in after missing Sunday's game with injury.
"We have to keep quiet and work like we did before and the season is going well".
Ramsey does want to stay in England, but Ramsey would be walking into an impressive side that has won the Serie A title seven years in a row.
