Arsenal have brought brilliantly in this summers transfer window but as yesterday's Champions League tie against Besiktas showed, Arsenal still need a defensive midfielder to complete their squad.
Although the game was a 0-0 draw, Arsenal were cut open on a number of occasions in a comparative fashion to the way they were battered by Manchester City, Liverpool and Chelsea last season.
In yesterday's game, Arsene Wenger switched from Arsenal's usual 4-2-3-1 formation to that of a 4-1-4-1, relying on one clear defensive midfielder instead of two.
The change did not work as Mikel Arteta (the designated) defensive midfielder failed to register a single tackle all game. After he came off with a an injury, his replacement Flamini, was typically yellow carded within five minutes.
This was a general problem last season as Arteta lacked the brute strength and industry to compete and Flamini was too undisciplined to be effective.
Under the 4-2-3-1 formation Arsenal played last season, this problem was masked when Aaron Ramsey was played alongside either of the aforementioned. The Welshman displayed the energy to help out, the nous to win tackles and the discipline to win tackles without drawing out fouls.
However, it appears Wenger wants to play the Welshman further forward so he can focus on his goalscoring exploits, in which case a top-class defensive midfielder is of paramount need.
Sami Khedira and Morgan Schneiderlin have been heavily mooted in the past weeks and months, however, for differing reasons it appears neither are likely to come to Arsenal.
Old flame Alex Song has been linked with a move too as well as PSG's Rabiot. In either case, Arsenal must make a move or else a season that promises to be so much could be unraveled when a big team comes to town again.
