Unai Emery ought to be very happy with how his summer signings at Arsenal have fared so far this season.
Bernd Leno, Sokratis Papastathopoulos and Matteo Guendouzi have all impressed when given the chance, while Stephan Lichtsteiner is a solid back-up to Hector Bellerin.
But the Spaniard's best signing has undoubtedly been Lucas Torreira, who joined from Sampdoria for approximately £27m.
Likened to Chelsea and France midfielder N'Golo Kante due to his playing style, Torreira is exactly what Arsenal have needed for a long time.
The 22-year-old is only 5' 5", but he's feisty and surprisingly strong due to his low centre of gravity, not to mention composed and creative going forward.
Martin Keown has certainly been impressed with what he's seen, saying recently: "I couldn't bear to watch Arsenal's away matches last season. Now they look much more competitive.
"As much as I enjoyed the confidence and expression of Aaron Ramsey's Harlem Globetrotter goal [against Fulham], what impressed me more was the grit, tenacity and determination.
TORREIRA'S A TERRIER
"They showed real character to win emphatically in the second half. Torreira has brought balance to the midfield. He has freed Granit Xhaka to be more creative.
"Until this match, it felt like Emery's Arsenal were a work in progress. On Sunday they bossed the game."
Arsenal fans have grown to adore Torreira's tenacity and fearlessness and they're going to love him even more after seeing what he did to Tottenham's Son Heung-min on Friday.
Uruguay and South Korea played out a 2-1 draw in Seoul and at one point Torreira put in such a hard, but fair, tackle that he injured both himself and Son. Check it out.
That's exactly what Arsenal paid for. For years the Gunners have lacked bite in midfield, but in Torreira they now have someone who's prepared to do the dirty work.
