Off the back of two narrow victories, one of Arsenal's stars has now issued a warning to his teammates ahead of their much-anticipated clash against Manchester United this weekend.
Official: Arsenal Star Returns To Barca
The Gunners are currently top of the Premier League standings five games into the new season.
The north Londoners have won all of their league matches so far, the only English team in the top flight, and one of only three sides in Europe's top five leagues, to boast such a record.
Granit Xhaka, who has now been at the club for six years, has attributed Arsenal's recent success to a mental shift within the squad.
"I think it was the biggest goal for us, to change this mentality," the Switzerland international said after Arsenal's 2-1 win over Aston Villa on Wednesday, as per the Evening Standard.
"I've been here seven (sic) years and I saw a lot of things, good and bad things, but we were always struggling a little bit in this way.
"You could play good football, everything looks good, but sometimes the 50-50 ball, the 50-50 games, you have to take it for you. I think today we won the 50-50 duels as well."
Here are 10 of the biggest deals that were completed on deadline day:
Despite having their best-ever start to a season since the 2004/05 campaign, though, the midfielder also warned that his team need to do better to "kill" games off as early as possible.
"We deserve the three points, I think, in the first five games," Xhaka continued.
"We have to learn, you can't always concede and come back like against Fulham or Villa, we have to try to finish and to kill the game before that."
On Sunday afternoon, the Gunners take on United at Old Trafford, a ground they have only won once at in the past decade. However, despite the Red Devils' erratic start to the season, Xhaka is not underestimating them.
"I know they are maybe not looking at the moment so good, but it's Manchester United. It's always difficult," the 29-year-old added.
"They are in the same position maybe that we were three years ago.
"They are building something as well. We have respect for them – but we go there to take the three points."
