I've dodged the question, thats pretty funny, for 3 years I've said firstly not getting rid of incredibly good ones for useless youth to come through was one option and buying a DM has been the main target every single season since Gilberto/Diarra left.
Its funny because for three years I've been told from Arsenal fans that Denilson, then Song were fantastic, why do we need others?
On the subject of the holding role, Wilshire has played the holding role all season so far, he was also the more defensive against Barcelona, only in the second half when seemingly Song was told to run away from anyone you might be tempted to hack down, did Song stay back more and Wilshire get forward more.
So my answer, Wilshire, and playing 2 DM's is ridiculous, because we were at our best when Song was scared to go forward and Wilshire helped support the attack more, or when we played more of a 4-4-2, with one DM, and took the game to a poor defence, which happened to work, which I suggested for WEEKS before the game.
Play Wilshire in the DM role he's played well all season and played for England, and put a decent ruddy attacking midfielder in alongside him. Cesc is great defensively anyway, he covers, he reads the game, he tackles and he can work under pressure, all the things that make Wilshire good there.
Personally I think the idea of forcing a crap player into a position YOU DON'T EVEN NEED, is a shockingly bad idea. Bendtner and RVP upfront, or push Diaby/Song/Denilson/other random crap player in alongside Wilshire.......
This would be the answer by the way, I've been giving for three years, dodging the question, if you say so. Packing the midfield with worse quality players, while not playing better players, making your midfield worse, and your attack weaker, is just completely stupid.
