Wenger made a major gaffe this past summer, regarding the defensive midfield position. Not by getting rid of Alex Song, who was no more a defensive midfielder than Cesc Fabregas.
No, Wenger's mistake was not recruiting Nigel De Jong to fill this key role. It was a move this author suggested and utter madness that the Gunners didn't at least enquire about his availability.
Perhaps Wenger can rectify the mistake this summer by adding Toulouse powerhouse Etienne Capoue. Arsenal need a robust, disciplined presence in front of their back four and Capoue fits the bill.
The key attribute of a defensive midfielder has to be first staying in front of his defense. That's why a move for reported target Mohammed Diame would have been a disaster.
Positional discipline, not buccaneering raids forward, has to come first. That's why Mikel Arteta has been reasonably successful in the role, because he maintains his position.
What he lacks in brute-force power, Arteta compensates for with sound awareness and intelligence. Capoue would offer the muscle also crucial at the position, either as a replacement, or in partnership with the veteran Spaniard.
According to talkSPORT.co.uk, Arsenal lodged an unsuccessful bid for Capoue in January. A fresh offer in the summer might be a smart move.
