1) Up front
Olivier Giroud has been in excellent form lately but losing Danny Welbeck for such a large chunk of the season leaves Arsenal awfully light up front. Even if Welbeck returns his goal scoring record in the Premier League for both Manchester United and Arsenal is far from impressive. Arsenal need a plethora of attacking options and whilst Theo Walcott has added to that (including a fine goal against Man City) the side are still light up front. They miss a genuine top class striker which is an issue, even if Giroud is scoring goals on a relatively regular basis at the moment.
2) Centre midfield
Arsenal have been short in the midfield for some time now. The fans cried out for the signing of a defensive midfielder in the summer but were disappointed. Wenger has lost out on Rosicky and Wilshere for parts of this season and whilst Aaron Ramsey is always in form when fit, he is too unreliable. The side should not still be playing Mathieu Flamini on a regular basis and undoubtedly need to bring in a top class holding player to add balance and more importantly at this stage reinforcements to the squad. It would also send out a message to the fans and the rest of the league that Wenger’s side mean business.
3) Defensive reinforcements
The defence has been quite good in recent weeks with Arsenal boasting one of the best defensive records in the league. The signing of Petr Cech undoubtedly helped solidify the side at the back. Last January the side brought in Gabriel Paulista but the Brazilian has not made much of an impact. The back four has been relatively settled but there is a feeling that the side could do with an upgrade at left-back. Alternatively it would be beneficial just to bring in numbers in order to bolster the squad, rather than to rest on their laurels until May.
