Arsenal sit two points clear at the top of the Premier League table heading into the international break, even after Sunday's 1-0 defeat to Manchester United.
Despite their excellent start, the Gunners are not expected to hold on to top spot for the remainder of the season and finally end their nine-year trophy drought by winning the Premier League trophy.
They need to strengthen in one or two areas of the pitch in order to mount a serious title challenge, which is exactly what Arsenal boss Arsene Wenger plans to do in the January transfer window.
Let's take a closer look at five dream signings for the Gunners…
5. Joe Hart | Manchester City
Yes, Wojciech Szczesny has been decent enough this season, but the signing of Manchester City's Joe Hart would be a significant upgrade.
The England No. 1 has endured a tough season, but form is only temporary, his class is permanent - and he'll be back to his excellent best before too long.
If Manchester City bring in another goalkeeper in January, Wenger should pounce for the shot-stopper he has long admired from afar.
4. Ilkay Gundogan | Borussia Dortmund
Arsenal don't need a midfielder, but it would be hard for Wenger to turn down the brilliant Borussia Dortmund star Ilkay Gundogan, who is wanted by some of Europe's top clubs.
The Germany international is only 23 years old and, subsequently, is still some years away from reaching his peak.
He would improve almost every team in the world, including Arsenal's.
3. Diego Costa | Atletico Madrid
Brazil-born future Spain international Diego Costa has been the talk of La Liga this season thanks to his stunning goalscoring exploits with title contenders Atletico Madrid.
The 25-year-old is currently second in Spain's top scorer charts, having netted 13 goals this term, and would be a superb signing for the Gunners.
Wenger missed out on Luis Suarez in the summer, but this South American striker isn't entirely dissimilar to the Liverpool star.
2. Karim Benzema | Real Madrid
Arsenal need another striker - and Wenger has reportedly identified Olivier Giroud's France teammate Karim Benzema as the perfect striker signing.
The Real Madrid star would cost Arsenal around the £30m-mark, but that is not a terrible price considering the calibre of player we're talking about.
Benzema's form has picked up recently, though, and Real Madrid coach Carlo Ancelotti may be tempted to keep him at the Bernabeu - at least until the end of the season.
1. Javier Hernandez | Manchester United
Mexico international Javier Hernandez has played the role of Manchester United super-sub for some time now - and as a result he's become a little frustrated recently.
The livewire striker is one of the most clinical strikers in the business and would be an asset for any team in the Premier League, including Arsenal.
Although he would find himself below Olivier Giroud in the pecking order at the Emirates Stadium, he'd still receive more first-team opportunities, and no doubt he'd be a major success.
