While Arsenal remain in the hunt to boost their squad before the end of the transfer window, there could still be several departures before Fridays' deadline. A number of players have failed to show the ability to take the Gunners back to seriously challenging for the game's major honors and Wenger would doubtless welcome bringing in extra money to help with his late recruitment drive. Here are five players who may have played their last game in an Arsenal shirt.

Nicklas Bendtner
Incredibly the perennially-confident Dane is still around. Though that could well change in the next week. After failing to fulfill his potential on a consistent basis for the Gunners, Bendtner was sent on a loan to Sunderland last season. The 24-year-old failed to shine there either and also had problems off the pitch which again left his future in limbo. His performances for Denmark show there is a good player in there, thought it looks all but certain that his potential won't now be realized at the Emirates.

Wenger has confirmed that Bendtner may well leave before the end of the window, with a host of clubs, including Milan and Juventus, thought to be interested.

Theo Walcott
Reports in Wednesday claim that the winger has turned down Arsenal's contract offer of £75,000 a week. Although Walcott has just 12 months remaining on his current deal, it is believed that the club have agreed to keep the England international for the time being. However with the risk of losing him for nothing next summer, a bid of around £15 million may seriously test the Gunners resolve.

While Wenger has claimed he wants Walcott to stay, his loss is unlikely to be viewed with the same anguish as that which accompanied the departure of Robin van Persie. Walcott's pace is a constant threat, but he has failed to develop the other areas of his game as his manger would surely have hoped since arriving form Southampton as a 16-year-old in 2006. With Alex Oxlade-Chamberlain, Gervinho and even Santi Cazorla capable of operating on the right as well as high expectations of youngster Serge Gnabry, the loss of Walcott may well be countenanced. Liverpool and Manchester City are said to be interested.

Marouane Chamakh
When Chamakh arrived on a free transfer from Bordeaux two years ago it looked like being a superb piece of business as he hit the ground running, scoring regularly in the absence of the injured Van Persie . But ever since then the Morocco international has looked a shadow of that player, devoid of all confidence in front of goal.

The 28-year-old had a desperate time of things during the last campaign, making just one Premier League start and scoring a solitary goal in all competitions. Chamakh has said he wants to stay at the club, but Arsenal would surely consider selling should a reasonable offer arrive.

Andrey Arshavin
The Russia international's days at Arsenal looked over when he was allowed to move on-loan to Zenit St Petersburg for the second half of last season. Yet, the 31-year-old returned to the Emirates after Euro 2012 and appeared as a substitute in the opening Premier League game of the season.

Arshavin has fallen some way since becoming Arsenal's record signing in 2009 and hitting four goals against Liverpool in an early game for the club. But his inconsistency and often seeming lack of interest has come to frustrate Wenger as much as it does the supporters. The latest reports suggest Zenit may be set to make a £10 million offer; a scenario that should suit all parties.

Park Chu-Young
Eyebrows were raised when Arsenal swooped to sign the South Korea international from recently-relegated Monaco. Those initial expressions will not have changed since as the forward made just one substitute appearance in the Premier League and scored just the one goal, in the Carling Cup. Both Celta Vigo and Olympiacos have been linked with a move, with reports claiming that Arsenal would be willing to accept a nominal amount for the 27-year-old.
