no question, attacking midfielder. I believe in Giroud and Podolski... they don't need to set the world on fire, as long as they have a support system in place, they'll knock in the goals. I mean, we've been needing a replacement for Nasri/Cesc for the entire season... surely the board/Wenger realizes that given they went after RVP replacements already and were in for Mata up until the bitter end. Goddamnit, Mata, Hazard, Gylfi... any of those three would easily have filled the gaping hole in the number 10 position. maybe Belhanda, I guess he has a proven partnership with Giroud, but I'm not sure if he's world class in the same way Mata/Hazard are and we need a world class midfielder in that position if we want to compete for titles again. which I honestly believe is possible with this squad IF this signing is made.
after that, defensive midfielder as cover/rotation option for Song (M'Vila... please?). then full back (Baines is pricey... but would do the trick, no question. I'd prefer Debuchy but who knows if that's even a possibility). then if there's still cash left, experienced (age 25 at the very very minimum) center half/GK.
Walcott should fuck off. He probably wants to anyways, since he knows Wenger will never play him in his preferred position and if Chelsea really is in for him (why they would want him... I have no idea, but I'm not about to question this stroke of good fortune) then for the love of god, it's time to cash in. He's a shit winger, and we'll never know if he can be a striker so if we can get anything more than 10m, I'd be overjoyed. RVP's the last big name player of the trophyless era, might as well clean out the full house. it was a failed experiment, time to start anew. It'd be best for all parties involved; the fans frustrated with Walcott, Walcott frustrated with Wenger, and Wenger to be forced to admit that his little experiment with Walcott hasn't paid off.
