2, Defensive Mid-field
You will agree with me that this is a position that is germane to our success next season.Alex song for many seasons was the man in front of the back four saddled with the responsibility of breaking up play and shielding the defence from fast counter attacks when we lose the ball. As the years went by and Song's confidence increased it was evident that it was not a role he was ready to shoulder. He didn't like the dirty job the position of Defensive midfeild offered but also in fairness he lacked the tactical discipline required to be successful there. here is a case in point, rewind two seasons ago towards the end of the 2011-2012 season..our last home game at the emirates, where we clashed with Norwich FC, the game which pitched Arsenal as favorites turned out to be tougher than anyone expected. it ended in a 3-3 draw but what  was evident in that game was how Norwich employed the usage of Fast counter attacks to stun us countless times in that game. Song kept abandoning his primary defensive role and pushed up leaving us exposed dangerously to Norwich's fast breaks. Fast forward to 2013,Song isn't with Arsenal any more & Arteta who is an attacking Mid-feilder by nature has been played out of position there. i'll say this now Arteta is a good proffesional and credit to him fo not complaining about being played out of position but it was clear we cannot settle for that arrangement next season if we are serious about competing for trophies. We need a tactically aware player ready strong,quick,and preferably young to take up this position.
So who are the options? Lars Bender of Leverkusen, Victor Wanyama of Celtic, James Mccarthy of Wigan,Grenier of Lyon and Fellaini of Everton  have been linked to us via the rumour-ville. Grenier is french and Cheap! and we all know how that word CHEAP sounds in Wengers' ear so don't be surprised if its him at the end of the day. Fellaini was a sensational link early in June but lets face it,are we going to pay as much as £25 Million for him? remains to be seen...and stranger things have happened..but having put in a rejected £22million bid for the impressive German, Lars Bender it obviously means it is a position Wenger has already made up his mind to strengthen this season. The wait continues
