Shkodran Mustafi couldn't have hoped for a better start to his Arsenal career.
Since completing a £35 million move on August 30, the Germany international has made six appearances for the Gunners and won five of them, drawing the other to Paris Saint-Germain.
Alongside defensive stalwart Laurent Koscielny, Mustafi has gone from strength to strength and throughly impressed with a number of commanding performances.

Arsene Wenger certainly seems happy with his summer signing after claiming he "has the potential to become a great defender for Arsenal".
Fans have taken to Mustafi almost immediately and it's because of the following five moments that he's made such an excellent first impression.
PERFORMANCE VS CHELSEA & DIEGO COSTA
Mustafi's finest display in an Arsenal shirt so far came during a 3-0 win over Chelsea on September 24.
The German used his strength and aggression to not only keep a clean sheet, but also nullify the threat of Diego Costa.
A compilation video of Mustafi and Koscielny dealing with Costa emerged following the game (see above) and it's a brilliant watch.
Time and time again, Arsenal's defensive duo stunted the Spaniard with some hard tackles and gave him a taste of his own medicine.
REACTION TO FOUL AGAINST BURNLEY
What's apparent is Mustafi is quite a character.
Never one to bottle his emotions, the 24-year-old reacted brilliantly to giving away a free-kick against Burnley on Sunday.
After fouling Sam Vokes, Mustafi protested the decision by physically demonstrating how the striker had hold of his shirt - by using the referee.

HUDDLE AFTER BURNLEY WIN
Arsenal deserved a pat on the back following their 1-0 victory over Sean Dyche's side.
Koscielny's controversial late winner secured all three points but it was the way that Wenger's side kept plugging away that was impressive.
And Mustafi appreciated the effort his teammates had put in. Upon the final whistle, the German gathered the likes of Koscielny, Mesut Ozil and Nacho Monreal for a group huddle to celebrate their win.
It was a touching moment that reinforced Mustafi's qualities as a leader.
THEO WALCOTT: MUSTAFI'S A MOTIVATOR
Leadership has been lacking at Arsenal in recent years but in Mustafi, they have a player willing to take games by the scruff of the neck.
That's according to Theo Walcott, who recently explained how his new teammate isn't shy of expressing his emotions towards players.
He said: "Shkodran Mustafi gets people up for games. If you're not doing something right, he tells you - and that's great.
"He's a Germany international and that's the way he is. He's at a completely different level at this time."
TACKLES AND INTERCEPTIONS
In his short time at Arsenal, Mustafi has already built a reputation for his tough tackling and reading of the game.
On his debut against Southampton, for example, the former Valencia centre-back made a number of outstanding challenges and interceptions (see below).
It's still early days but Mustafi looks every bit a world-class defender, and alongside Koscielny, Arsenal potentially have a title-winning partnership.
Defence has long been a problem position at the Emirates Stadium but it seems £35 million has finally solved the issue.
