Alexis Sanchez was given his competitive debut for the Gunners, but in the absence of the club's recent World Cup winners, it was evident that the squad still needs to be strengthened.
Here, we take a look at the latest gossip surrounding the team from Emirates Stadium.
Arsenal are still in need of a top-class defensive midfielder, and it is no surprise that Cheick Tiote's name is being linked to the Gunners, a potential move that was reported by Metro.
John Wardle of the Mirror reports that Newcastle will allow the player to leave St James' Park if they receive an £8 million offer for the Ivory Coast international.
Wardle explains that Newcastle manager Alan Pardew is "bracing himself" in anticipation of losing Tiote, with Lokomotiv Moscow keen on purchasing the player, having had one bid for the midfielder already fail.
Crucially, Wardle says that Tiote wants to stay in the Premier League, which suits his style of play. But Mike Ashley, the owner of Newcastle, will make the final decision over any transfer.
On Thursday morning, Arsenal manager Arsene Wenger admitted that he is in the market for a defensive midfielder.
This would lead you to think he might be interested in the Newcastle man:
It was not that long ago that Tiote was thought to be worth a lot more than £8 million, and his current price would surely be attractive to Wenger.
Tiote has tremendous Premier League experience and showed at the recent World Cup that he still is an excellent player.
Tiote has suffered with injury in the past, but his health has been excellent for the past two years, playing 57 times in the Premier League for the Geordies, per WhoScored.com.
However, he did miss Newcastle's opening day defeat to Manchester City due to a hamstring injury, per Wardle.
Arsenal need to strengthen their defence, both in their back four and midfield. The team's best defensive player in the first two competitive games of the season has been teenager Calum Chambers, showing the lack of depth surrounding the young new recruit. Neil Ashton of the Daily Mail highlighted the player's impact:
Arsenal cannot rely on a teenager to hold their defence together for a whole season, and an experienced player sitting in front of him is badly needed.
Tiote would work well with Chambers and the other defenders and would offer the Arsenal goal some vital extra protection.
Whether Wenger officially moves for Tiote is yet to be seen, but if he is to shore up his defence in the next week, he might not find any better value in the market than the Newcastle player.
Chisanga Malata of the Daily Star says that Arsenal have had a £20 million bid for the player rejected by his club, Sporting Lisbon.
And 101 Great Goals highlights that Portuguese paper A Bola has the potential deal on the front page of its publication, implying that Arsenal will return with a higher offer.
Sporting chairman Bruno de Carvalho was recently asked if any move was in the pipeline for Carvalho, per Malata, with the supremo simply saying, "For William, there are no proposals."
Carvalho's stock has exploded in the past 12 months, and if Wenger wants a tough defensive player, the Sporting midfielder will fit the bill.
But he will need time to develop and may be of less use to Wenger immediately than a player such as Tiote.
Fresh from his Brazilian adventure, which saw him lift the World Cup, Lukas Podolski could be on yet another journey—this time out of London to Turkey.
Sam Adams of the Mirror says that Arsenal are "happy" to sell the German attacker to Galatasaray but will not sell Joel Campbell, who the Turkish giants also want.
Podolski's agent, Nassim Touihri, confirmed to Bild that his client might be on the move, per 101 Great Goals.
"There have always been questions," Touihri said. "Now we have a concrete interest from some teams. Lukas is in London, and he feels good."
Podolski is a fading force at both the club and international levels, but his record for the Gunners was useful last season despite being on the fringes of the team.
In his 20 Premier League appearances last year, Podolski scored eight times, per WhoScored.com, proving he still knows where the goal is.
Podolski would be little loss to Arsenal if the Gunners can get Theo Walcott fit and keep him fit.
And with the inclusion of Sanchez this term, Podolski's time on the pitch will be further reduced. Adams says that Wenger is prepared to move Podolski out before the end of the window, and Galatasaray would surely be a good option for the player.
He may not be good enough for the elite leagues anymore, but the standard of Turkish domestic football is good, and he would shine in their team.
