I think Wenger wants Draxler to be more of a foward, but definitely not a striker! Draxler can bery well be a downgraded version of Ronaldo, they actually share way more similarities than most think and Arsenal are in huge needs of a great player for that left wing (or however you want to call it). If this indeed goes through (which I doubt, since Schalke will want a good fee and Wenger already spent big in August), I imagine Arsenal playing something like a 4-3-2-1: Szczesny / Sagna, Koscielny, Vermaleen, Monreal / Wilshere, Ozil, Ramsey / Draxler, Walcott / Giroud. With some good subs: Flamini, Arteta, Cazorla, Podolski, Chamberlain, etc... That would be a totally different aproach and mentality than if they went for a striker like Diego Costa, but it is still interesting to them!
