As the 2014-2015 season enters its second leg, Arsenal boss Arsene Wenger will have the opportunity to make a few January changes to his squad.
Apart from looking to other leagues to bring in more reinforcements, Wenger can try making moves for players in the same league as some big name players are tipped to be on the move.
So, here are five Premier League players the Gunners should look to if they will want to regain their form and fight for a top four finish again...
Winston Reid
Name: Winston Reid
Age: 26
Position: Centre-Back
Nationality: New Zealand
Club: West Ham United
Price: £20million (asking price)
Arsenal have more than once shown that they are struggling to defend week in week out and with their added injury concerns in the back, another centre-back sure tops Arsene Wenger's January shopping list.
Winston Reid has been in great form helping West Ham United achieve a great first half of the season as he is also being linked with moves to Liverpool and Manchester United. However, his huge asking price is still a factor in his purchase with Wenger not willing to spend such a high fee for his services.
Morgan Schneiderlin
Name: Morgan Schneiderlin
Age: 25
Position: Centre Midfield
Nationality: France
Club: Southampton
Price: £20-£25million
Apart from needing to buy a centre-back, Arsenal are also in desperate need of a central midfielder capable of slotting in right in front of the back four. Attack-wise, Arsene Wenger has a huge selection of players while both Mikel Arteta and Mathieu Flamini have been on the recieving end of quite a bit of criticism.
Morgan Schneiderlin has been linked with a move to the Emirates ever since the summer, but Ronald Koeman is doing all he can to retain his services. It is likely that the Gunners will put together one big offer to finally fill the void in their midfield.
Chris Smalling
Name: Chris Smalling
Age: 25
Position: Centre-back
Nationality: England
Club: Manchester United
Price: £10-£15million
Although this is a highly unlikely transfer, Arsene Wenger was linked with a move to try and sign Chris Smalling from rivals Manchester United. With Arsenal only having two actual centre-backs in their squad, signing another one is in the club's best interest.
Smalling may even be open to a move if Louis van Gaal decides to reshuffle his entire defence given the way they have been playing lately. If United sign one or two centre-backs in January, Wenger may be cleared to make a move for the England defender sometime during the January window.
Moussa Sissoko
Name: Moussa Sissoko
Age: 25
Position: Centre Midfield
Nationality: France
Club: Newcastle United
Price: £15-£20million
Moussa Sissoko is a player who fits the bill to fill the role Arsene Wenger is looking for and given Newcastle United's struggle so far this season, he may be interested in a switch to the Emirates. He has featured in 18 out of 20 games for his side and is a constant powerhouse in the middle of the park.
With Alan Pardew about to leave the club, this could be the perfect time for Wenger to make a move as the future of a number of players will be uncertain given a change in management. His defensive capabilities and attacking abilities could be exactly what the Gunners need heading into the final months of the campaign.
Ron Vlaar
Name: Ron Vlaar
Age: 29
Position: Centre-back
Nationality: Netherlands
Club: Aston Villa
Price: £10-£15million
Ron Vlaar is another centre-back that has been attracting interest from a number of Premier League clubs, with Liverpool and Manchester United also linked. Arsene Wenger is in desperate need for an experienced defender to either take over from his current ones or serve as back up should someone get injured.
Having been forced to play both Calum Chambers and Mathieu Debuchy in the middle of his defence throughout the season, Wenger should be aiming to secure Vlaar in January so he has enough cover going into the second half of the campaign.
